The warranty does not apply to units subject to misuse, battery leakage, neglect or accidents. Nor does the warranty apply to units damaged by lightning, excess current, moisture, units repaired or altered outside the factory, units with altered or removed serial numbers, or units used with accessories other than those approved by the factory. To have your unit serviced under this warranty, return it postage paid with proof of purchase to:
Sportys Pilot Shop Clermont County/Sportys Airport 2001 Sportys Drive Batavia, Ohio 45103-9719 If your L6 COM is no longer under warranty, you may still have it serviced at Sportys. See above for return address instructions. Antenna Requirements Included with the L6 COM is a exible rubber antenna (Rubber Duck). However, an external antenna may be needed if operating inside an aircraft (must be properly installed by an aircraft radio shop), automobile or other metal enclosure. On top of the L6 COM is a BNC connector , which is standard for use on aircraft radios. Therefore, little difculty should be encountered in connecting an existing aircraft radio antenna to the L6 COM. 6 Manual_final.indd 6 Manual_final.indd 6 7/13/22 1:51 PM 7/13/22 1:51 PM Batteries An Alkaline Battery Pack is standard equipment with the L6 COM. Alkaline batteries are a good power source for a backup radio because they have excellent storage life and no maintenance is required. The Alkaline Battery Pack is NOT rechargeable. The batteries must be replaced. To replace the batteries, turn the power OFF and then remove the battery pack from the unit by holding the belt clip (if installed) in the out position, and then lift the latch mechanism found at the bottom of the battery pack. Remove the battery cover by pulling the thumb latch in the direction of the arrow. Six 1.5 volt AA Alkaline batteries are required. Energizer batteries are the recommended battery for the L6 COM. Results may vary when using off brand batteries. Replace the batteries by following the positive (+) and negative (-) terminal markings inside the case. When the batteries are replaced, replace the battery cover and attach the battery pack to the radio. To attach the battery pack, make sure the power is OFF. Slide the battery pack onto the back of the and push in on the bottom until it locks in place. If the radio will not be used for a long period of time (six months or more), please remove the batteries from the battery pack. This will help prevent the batteries from corroding the battery pack. 7 Manual_final.indd 7 Manual_final.indd 7 7/13/22 1:51 PM 7/13/22 1:51 PM External Power The L6 COM includes a wall adapter and USB-A to USB-C power cable. The wall adapter can be used in 100-240 volt applications. The USB-A on the wall adapter provides the needed 2.4 amps to properly power port the L6 COM. If less than 2.4 amps is provided, the L6 COM will receive transmissions, but it wont have enough power to transmit. If attempting to transmit on less than 2.4 amps, the L6 COM screen will ash intermittently and beep. To remedy this issue, change the power source to provide the needed 2.4 amps, or use the alkaline battery pack. The L6 COM does not have power delivery capability. Power should only be provided from a USB-A port. Another option for external power is to use a backup tablet battery pack
(sold separately). Be sure to use a battery pack that provides at least 2.4 amps of power. Note: When powering the L6 COM through the Type-C power port on the side of the radio, the radio will transmit at 5 Watts (PEP). 8 Manual_final.indd 8 Manual_final.indd 8 7/13/22 1:51 PM 7/13/22 1:51 PM Precautions:
Changes or modications not expressly approved by the manufacturer for compliance could void the users authority to operate the equipment. Never attempt to service this unit yourself. It should be referred to qualied service personnel. Please read the Warranty section in this manual. If liquid spills or some solid object falls into the unit, remove the battery pack or external power adapter and have the unit checked by a qualied person before further operation. Never dispose of batteries or battery packs in a re. They may explode. Never leave weak or dead batteries in the Alkaline Battery Pack. They may leak and cause permanent damage. Never store a battery pack where it may be accidentally shorted. Use only the approved external power adapters and battery packs. Never touch an external antenna when the danger of lightning is present. Do not leave the transceiver near heat sources, such as radiators or air ducts, or place the transceiver in an environment where the radio will be subjected to moisture, excessive dust, shock or mechanical vibration. Abrasive cleaners or chemical solvents may mar or damage the case. Clean the transceiver with a soft cloth dampened with a mild detergent solution. If operating the transceiver at temperatures outside the range of
-20F to 122F (-30C to 50C), the LCD (screen) may not display the selected frequency. If the L6 COM is used in temperatures lower than the recommended range, the characters being displayed may change very slowly. These irregularities will disappear, with no harm to the L6 COM, when operation is resumed within the recommended temperature range. 9 Manual_final.indd 9 Manual_final.indd 9 7/13/22 1:51 PM 7/13/22 1:51 PM Controls This section servesonly to identify and briefly describethe L6 COMs external features.

(U) Manual.indd 13 8/9/19 5:46 PM Operating Instructions To perform the following functions you must be in the basic operating mode of the L6 COM. To ensure that you are in the basic operating mode, press the Clear key until the last frequency that was entered manually is displayed. Manual Frequency Selection The L6 COM will receive and transmit on the 760 COM frequencies (
118.000 MHz to 136.975 MHz). The frequency currently selected is always displayed at the top of the L6 COMs screen and the last frequency is always underneath the current frequency. From the example above, the L6 COM is receiving 122.975 MHz with the last frequency being 121.000 MHz. To manually enter a desired frequency such as 118.700 MHz, enter 1 1 8 7 0 0 using the numeric keypad. As each digit is entered, the ashing cursor moves to the next digit. Six digits may be required to select a frequency. The L6 COM will return to the previous frequency if there is a pause of ve seconds between key entries while entering a new frequency. The Clear key may be pressed at any time prior to entering the sixth digit to clear the digits entered and return to the previous frequency. Any frequency outside of the range listed above will not be accepted. The L6 COM will beep when such a digit is entered. For example, starting any frequency selection with a number other than 1 or attempting to place a 5, 6, 7, 8 or 9 in the second digit will result in a beep. The L6 COM can ip op between the current frequency and the last requency by pressing the button above the PTT on the side of the radio. 14 Manual_final.indd 14 Manual_final.indd 14 7/13/22 1:51 PM 7/13/22 1:51 PM Frequency Search To manually search through the frequency range, the Up key or Down key may be pressed at any time to select the next higher or lower frequency. The Up and Down keys may be pressed repeatedly to continue changing the selected frequency. To automatically search the entire frequency range for a broadcasting signal, the Up key or Down key may be pressed and held for one second. The Screen will display SEARCH as seen below. The frequencies will either scroll up or down depending upon whether the Up or Down key was used to initiate the Search. When a broadcasting signal is found, the word SEARCH will ash and the L6 COM will stop temporarily on that frequency. If the broadcasting signal is cut off for more than two seconds, the Search will resume until another signal is found. When 136.975 MHz is reached during a upward Search, the Search automatically continues at 118.000 MHz. Likewise, when 118.000 MHz is reached during a downward Search, the Search automatically continues at 136.975 MHz. The Search may be canceled at any time by pressing the Clear key. The direction of the Search may also be reversed at any time by pressing and holding the Up and Down key (whichever is appropriate) for one second. It is very important that the Squelch be properly adjusted prior to initiating a Search. The background static received with the squelch off may be strong enough to disrupt a Search. If a Search gets stuck on a frequency with too much background noise, increase the Squelch or press and hold the Up or Down key for one second to skip that frequency and resume Searching. 15 Manual_final.indd 15 Manual_final.indd 15 7/13/22 1:51 PM 7/13/22 1:51 PM Frequency Memory The L6 COM has 20 visual memory channels numbered 00 to 19 to store those frequencies used most often. These channels are stored in groups of ve on four separate pages. These memory channels may be used to store COMM and WX frequencies. Select a desired frequency, such as 122.700, to be stored by using either manual frequency selection or frequency search. To store this frequency, press the Memory key. The following screen will appear. The rst available memory channel will be displayed with an arrow on the screen. In this example, memory channel 06 is the rst available location. To store the frequency, press the Memory key a second time. The screen will now display the following for one second to verify 122.700 has been stored in memory channel 06. 16 Manual_final.indd 16 Manual_final.indd 16 7/13/22 1:52 PM 7/13/22 1:52 PM You may also overwrite an existing memory channel or select an available memory channel other than the rst one displayed. Once again, select the desired frequency and then press the Memory key. The rst available memory channel will be displayed with an arrow on the screen. Now press either the Up or Down key to scroll through the 20 memory channels. If a memory channel is already storing a frequency, the stored frequency will be displayed next to the memory channel number on the screen while your selected frequency remains on the top line. Once the desired memory channel is selected, press the Memory key and the frequency will be stored. Remember, if a channel was selected that was already storing a frequency, the old frequency will be erased when your selected frequency is stored. You may exit the memory function by pressing the Clear key any time prior to storing the frequency (pressing the Memory key the second time). 17 Manual_final.indd 17 Manual_final.indd 17 7/13/22 1:52 PM 7/13/22 1:52 PM Memory Recall To recall a frequency stored in a memory channel, press the Recall key. The rst ve memory channel numbers and their corresponding frequencies will be displayed. The rst stored memory channel immediately becomes the active frequency and is received by the L6 COM. In this example, memory channel 00 is listed rst. At this point you may select any stored memory channel by either pressing the Up or Down key to scroll through the stored frequencies. Memory channels stored on other pages may also be accessed directly by using the numeric keypad. For example, to receive memory channel 08 you may either:
1. Press the Recall key followed by the Up or Down key to scroll to 08 Or 2. Press the Recall key followed by 0 8 Once in the Recall function, the L6 COM stays in Recall until the Clear key is pressed. This allows you to sequence your frequencies in the order you may wish to use them. For example, you may wish to store your airports ATIS in memory channel 00, Clearance Delivery in channel 01, Ground in channel 02, Tower in channel 03 and Departure Control in channel 04. For this example, you would press the Recall key once followed by the Down key for every frequency change instead of having to enter each frequency manually. While in the Recall function the only entries accepted are numeric entries between 00 and 19, the Up or Down key or the Clear key. All other inputs cause the L6 COM to beep. Remember, you may press the Clear key at any time to exit the Recall function. Once you have left the Recall function, the L6 COM will remain on the last frequency that was received. being 18 Manual_final.indd 18 Manual_final.indd 18 7/13/22 1:52 PM 7/13/22 1:52 PM Memory Scan The Memory Scan function is very similar to the Search function, except it only scans those frequencies stored in the memory channels. To Scan the memory channels, press the Recall key to enter the Recall function. Then press and hold the Up or Down key for one second to initiate either an upward or downward Scan. The word SCAN will appear on the screen and the memory channel number and frequency will be displayed on the top line of the screen. L 6 COM will stop temporarily When a broadcasting signal is found , the word SCAN will ash and on that frequency . If the the broadcasting signal is cut off for more than two seconds, the Scan will resume until another signal is found. The Scan may be canceled at any time by pressing the Clear key. The direction of the Scan may also be reversed at any time by pressing and holding the Up or Down key (whichever is appropriate) for one second. Once you have pressed the Clear key to exit a Scan, you are still in the Recall function. Press the Clear key again to exit the Recall function. The L6 COM will remain on the last frequency received. It is very important that the Squelch be properly adjusted prior to initiating a Scan. The background static received with the squelch off may be strong enough to disrupt a Scan. If a Scan gets stuck on a frequency with too much background noise, increase the Squelch or press and hold the Up or Down key for one second to skip that frequency and resume Scanning. Please note, since ATIS broadcasts continually, a Scan will always stop on an ATIS frequency if it is included in the Scan. 19 Manual_final.indd 19 Manual_final.indd 19 7/13/22 1:52 PM 7/13/22 1:52 PM Memory Clear To clear or erase a memory channel, press and hold the Clear key followed by the Memory key. Release the keys when MEM CLR is displayed on the top line of the screen. The rst ve memory channels with stored frequencies will be displayed on the screen. Press the Up or Down key to scroll through the memory channels to select the memory channel to clear. Once the desired memory channel is displayed, press the Memory Clear key (also the 0 key on the numeric keypad) to clear the selected channel. Additional channels may be cleared by once again pressing the Up or Down key to make another selection and then pressing the Memory Clear key. Press the Clear key at any time to exit the Memory Clear function. To clear every memory channel, hold down the Clear key while turning on the power. Please note, there is no way to reverse this process.
