PrecaUtioNs Do not charge the transcever and battery pack when they are wet. Ensure that there are no metallc tems located between the transcever and the battery pack. Do not use optons not specfed by kenwood. If the de-cast chasss or other transcever part s damaged, do not touch the damaged parts. If a headset or headphone s connected to the transcever, reduce the transcever volume. Pay attenton to the volume level when turnng the squelch off. Do not place the mcrophone cable around your neck whle near machnery that may catch the cable. Do not place the transcever on unstable surfaces. Ensure that the end of the antenna does not touch your eyes. When the transcever s used for transmsson for many hours, the radator and chasss wll become hot. Do not touch these locatons when replacng the battery pack. Do not mmerse the transcever n water. Always swtch the transcever power off before nstallng optonal accessores.
Turn the transcever power off n the followng locatons:
In explosve atmospheres (nflammable gas, dust partcles, metallc powders, gran powders, etc.). Whle takng on fuel or whle parked at gasolne servce statons. Near explosves or blastng stes. In arcrafts. (Any use of the transcever must follow the
nstructons and regulatons provded by the arlne crew.) Where restrctons or warnngs are posted regardng the use of rado devces, ncludng but not lmted to medcal facltes. Near persons usng pacemakers. Do not dsassemble or modfy the transcever for any reason. Do not place the transcever on or near arbag equpment whle the vehcle s runnng. When the arbag nflates, the transcever may be ejected and strke the drver or passengers. Do not transmt whle touchng the antenna termnal or f any metallc parts are exposed from the antenna coverng. Transmttng at such a tme may result n a hgh-frequency burn. If an abnormal odor or smoke s detected comng from the transcever, swtch the transcever power off mmedately, remove the battery pack from the transcever, and contact your Kenwood dealer. Use of the transcever whle you are drvng may be aganst traffc laws. Please check and observe the vehcle regulatons
n your area. Do not expose the transcever to extremely hot or cold condtons. Do not carry the battery pack (or battery case) wth metal objects, as they may short the battery termnals. When operatng the transcever n areas where the ar s dry, t
s easy to buld up an electrc charge (statc electrcty). When usng a earphone accessory n such condtons, t s possble for the transcever to send an electrc shock through the earphone and to your ear. We recommend you use only a speaker/

7 OPERATING THROUGH REPEATERS Repeaters are often installed and maintained by radio clubs, sometimes with the cooperation of local businesses involved in the communications industry. Compared to simplex communication, you can usually transmit over much greater distances by using a repeater. Repeaters are typically located on mountain tops or other elevated locations. They generally operate at higher ERP (Effective Radiated Power) than a typical station. This combination of elevation and high ERP allows communications over considerable distances. TX: 44.725 MHz TX tone: 88.5 Hz RX: 45.325 MHz TX: 44.725 MHz TX tone: 88.5 Hz RX: 45.325 MHz
8 repeAter AcceSS Most repeaters use a receive and transmit frequency pair with a standard or non-standard offset (odd-split). In addition, some repeaters must receive a tone from the transceiver in order to gain access to the repeater. For details, consult your local repeater reference. Selecting an Offset Direction The offset direction allows your transmit frequency to be higher (+) or lower () than the receive frequency. 1 Press [F], [8] to select an offset direction. Continually press [F], [8] to toggle the functions as follows:
+ >> >> OFF. 2 Press any key other than the Selector (or [UP]/ [DOWN]) to store the setting. The or icon appears above the frequency, indicating which offset direction is selected. If the offset transmission frequency falls outside the allowable range, transmission is inhibited. In this case, adjust the reception frequency so that the transmission frequency is within the band limits. Note: While using an odd-split memory channel or transmitting, you cannot change the offset direction.
9 Selecting an Offset Frequency To access a repeater which requires an odd-split frequency pair, change the offset frequency from the default which is used by most repeaters. 1 Enter Menu mode and access Menu No. 2 (OFFSET). 2 Press [MENU] and rotate the Selector (or press [UP]/
[DOWN]) to select the appropriate offset frequency value. The selectable range is from 00.000 MHz to 29.950 MHz, in steps of 50 kHz. Note: After changing the offset frequency, the new offset frequency will also be used by Automatic Repeater Offset. ActiVAting the tone Function Press [F], [1] to turn the Tone function ON. Continually press [F], [1] to toggle the functions as follows: Tone ON >> CTCSS ON >> DCS ON >> OFF. The icon appears when the Tone function is ON. Selecting A tone Frequency To select the tone frequency required to access your desired repeater:
1 Press [F], [2]. The current tone frequency appears on the display. The default frequency is 88.5 Hz. 20 2 Rotate the Selector (or press [UP]/ [DOWN]) to select your desired frequency. 3 Press any key other than the Selector (or press [UP]/ [DOWN]) to store the setting.

45.00 ~ 45.499 MHz: Minus () offset
45.500 ~ 45.599 MHz: No offset (Simplex operation)
46.000 ~ 46.399 MHz: Plus (+) offset
46.400 ~ 46.599 MHz: No offset (Simplex operation)
46.600 ~ 46.999 MHz: Minus () offset
47.000 ~ 47.399 MHz: Plus (+) offset
47.400 ~ 47.599 MHz: No offset (Simplex operation)
47.600 ~ 47.999 MHz: Minus () offset
48.000 MHz and higher: No offset (Simplex operation) 23 reVerSe Function After setting a separate receive and transmit frequency, you can exchange these frequencies using the Reverse function. This allows you to manually check the strength of signals you receive directly from other stations, while using a repeater. If the stations signal is strong, move to a simplex frequency to continue the contact and free up the repeater. Press [F], [7] to turn the Reverse function ON or OFF. When the Reverse function is ON, the icon will appear on the display. Note:
If the transmit frequency is outside the allowable transmit frequency range when using Reverse, pressing [PTT] will cause an error tone to sound and transmission will be inhibited. If the receive frequency is outside the receive frequency range when using Reverse, an error tone will sound and Reverse will not operate. The ARO (Automatic Repeater Offset) will not function when Reverse is ON. You cannot switch Reverse ON or OFF while transmitting. AutoMAtic SiMplex checker (ASc) While using a repeater, ASC periodically monitors the strength of signals you receive directly from the other stations. Press [7](1s) to turn the ASC function ON or OFF. When the ASC is ON, the icon will appear on the display. 24 While direct contact is possible, without the use of a repeater, the icon will blink. Note:
Pressing [PTT] will cause the icon to stop flashing. ASC does not function if you are using simplex operation. ASC does not function while scanning. Activating ASC while using Reverse will switch the Reverse function OFF. If you recall a Memory channel or the Call channel, and those channels are set up with the Reverse function switched ON, the ASC will switch OFF. ASC causes received signals to be momentarily intermitted every 3 seconds. 25 MEMORY CHANNELS In memory channels, you can store frequencies and related data that you frequently use so that you do not need to reprogram that data every time. You can quickly recall a programmed channel through simple operation. A total of 100 memory channels (50 when using the Memory Name function) are available for storing frequencies, modes and other operating conditions.
