This apparatus is capable of two-way communication on channels used for critical aviation safety communications. Therefore, it is important that this radio be kept away from children or other unauthorized users at all times.

When making DC connections via the (optional) E-DC-5B DC cable, be absolutely certain to observe the proper voltage level and polarity guidelines. Do not connect this radio directly to any 24 ~ 28 Volt DC source, nor to AC power of any kind. Connecting the VXA-300 directly to a source which exceeds 15.0 Volts DC will result in damage to the unit.

Do not dispose of the Ni-Cd Battery Pack in a fire. Do not carry a Ni-Cd Battery Pack in your pocket, where keys or coins could short the terminals. This could create a serious fire/burn danger, and possibly cause damage to the Ni-Cd pack.

Although the VXA-300 is designed to be water resistant, the enclosure is not waterproof. Do not allow the radio to become submersed in water, and do not expose it and/or its Ni-Cd Battery Pack to water spray under pressure. Battery Installation and Removal

To install the battery, hold the transceiver with your left hand, so your palm is over the speaker and your thumb is on the top of the Belt Clip. Insert the battery pack into the battery compartment on the back of the radio while tilting the Belt Clip outward, then close the Battery Pack Latch until it locks in place with a Click.

To remove the battery, turn the radio off and remove any protective cases. Open the Battery Pack Latch on the bottom of the radio, then lift the battery upward and out from the radio while tilting the Belt Clip upward. Do not attempt to open any of the rechargeable Ni-Cd packs, as personal injury or damage to the Ni-Cd pack could occur if a cell or cells become accidentally short-circuited. It is necessary to fully charge the Ni-Cd battery before its first use. Follow these procedures:

Install the supplied FNB-64 Ni-Cd battery pack onto the transceiver. Ensure that the Battery Charging transceiver is switched off.

Plug the NC-?? into the AC line outlet. 4/21 Vertex Standard Co., Ltd. FCC ID: K6610573X20 IC ID: 511B-10573X20 Operating Manual

Insert the transceiver and battery pack into the NC-??; the antenna jack should be at the left side when viewing the charger from the front.

If the transceiver and battery pack are inserted correctly, the RED indicator will glow. A fully-discharged pack will be charged completely in 10 hours. transmission). Important Notes:

The NC-?? is not designed to power the transceiver for operation (reception or

Do not leave the charger connected to the transceiver for continuous periods in excess of 24 hours. Long term overcharging can degrade the Ni-Cd battery pack and significantly shorten its useful life.

If using a charger other than the NC-??, or if using a battery pack other than the FNB-64, follow the appropriate instructions provided with the charger/battery. Contact your Dealer if you have any doubts about the appropriateness of the particular charger or battery pack you intend to use. Low Battery Indication

As your battery discharges during use, the voltage will gradually become lower. When the battery voltage reaches 6.0 Volts, the BATTERY icon will blink on the LCD display, indicating that the battery pack must be recharged before further use.

Avoid recharging Ni-Cd batteries before the Low Battery indicator is observed, as this can degrade the charge capacity of your Ni-Cd battery pack. Vertex Standard recommends that you carry an extra, fully-charged pack with you so you will not lose communications capability due to a depleted Ni-Cd battery. This Deep cycling practice will help to maintain longer overall battery life after many recharging cycles.

Scanning Operation The VXA-300 allows you to scan automatically in the VFO*1, Main Memory, Book Memory, or Weather Channel*2 modes. It pauses on signals encountered, so you can talk to the station(s) on that frequency, if you like.

*1: In the VFO mode, the automatic scanner is only available in the COM band (118.000 -

136.975 MHz); when the scanner reaches the uppermost frequency in the COM band, it will revert to the bottom end of the COM band and repeat the scanning process until you cancel the scanning process.

*2: USA version only. If you wish to scan in the NAV band (108.000 - 117.975 MHz), you can do so manually, as described at the right. Scanning operation is basically the same in each of the above modes.

Press and hold the [SCAN(DW)] key for 2 seconds to start the automatic scanner upward (toward a higher frequency or a higher channel number).

When the scanner encounters a signal, scanning pauses and the radio remains on that channel until one second after the signal disappears, after which scanning will resume.

While the scanner remains paused on a frequency, the decimal point of the frequency display blinks. The display will be illuminated unless the Scan Lamp Feature is turned off.

To change the scan direction, turn the DIAL selector knob one click in the opposite

To stop the automatic scanner, press the PTT switch or the VOLUME knob momentarily. You may also just press the [SCAN(DW)] key. The VXA-300s automatic scanner is not operational in the NAV band (108.000 - 117.975 MHz), because the NAV stations (ILS, etc.) transmit constantly (thereby causing the scanner to stop repeatedly). However, you can scan manually in the NAV band, per the following procedure:

Press and hold the [SCAN(DW)] key to start the manual scanner. Scanning will continue as long as the key is depressed.

Release the [SCAN (DW)] key to stop the manual scanner immediately. Note: When scanning upward in frequency, when the frequency reaches the COM Band

(118.000 - 136.975 MHz) via manual scanning, The VXA-300 will switch to the automatic scanner mode. Channel-Skip Scanning Continuous-carrier stations like ATIS (Automatic Terminal Information Service) or Weather Broadcast stations inhibit scanner operation. Since these stations are always active, the scanner will be halted repeatedly on their channels. Such channels can be set to be skipped during Memory scanning (MR, Book or WX modes), if you like, so as not to interfere with automatic channel scanning:

Recall the Memory Channel to be skipped during scanning.

Press [F] [9(SKIP)]. The SKIP icon will appear at the upper right of the channel number, indicating that the channel is to be ignored during scanning.

You can also designate a channel to be skipped while scanning. When the receiver is halted on a channel that you wish to skip, press and hold the [SCAN(DW)] key for 2 seconds (the SKIP icon will appear next to the channel to be skipped).

Later, to re-enable the memory channel for scanning, repeat the first two steps. The SKIP icon will disappear by the channel you have just re-enabled. Note: A memory set to be skipped is still accessible for manual memory selection using the DIAL selector knob. 12/21 Vertex Standard Co., Ltd. FCC ID: K6610573X20 IC ID: 511B-10573X20 Operating Manual Dual Watch Operation The Dual Watch feature automatically checks for activity on a priority channel* while you are operating on another channel. During Dual Watch operation, the current channel and the Priority channel will each be polled for a 500 ms interval, as the VXA-300 looks for activity on each channel.

To start Dual Watch, press [F] [SCAN(DW)].

The DW icon will appear on the display.

While receiving on the current channel (not the Priority channel), you may push the PTT switch at any time to transmit on that channel.

When a signal is received on the Priority channel, operation immediately shifts to the Priority channel, the DW icon will blink, and the display will become illuminated.

While receiving on the priority channel, if you momentarily press the PTT switch, Dual Watch will be disabled. You may then transmit on the Priority Channel.

To stop Dual Watch, press [F] [SCAN(DW)].

If you wish, you may use both the Dual Watch and Scan features simultaneously. To do this, start the Dual Watch first, then start the Scanner.

*: The priority Channel is defined as the last-used Memory Channel (when using the VFO mode) or Memory Channel 1 (when using the Main Memory or Book Memory modes). Priority Dual Watch Operation Similar to Dual Watch operation (described on previous page), Priority Dual Watch is an enhanced version which includes the following additional features:

The receiving time interval (ratio) between the current channel and the Priority channel may be customized via the Menu Item 09 PRTM. See page ?? for details.

Irrespective of which channel is currently being received, when the PTT button is pushed transmission will always occur on the Priority channel. Before initiating Priority Dual Watch, Menu Item 10 DWMD must be set to the PRI:

Priority mode (instead of DW: Dual Watch). See page ?? for details.

To start Priority Dual Watch, press [F] [SCAN(DW)]. The DW icon will appear on the

While receiving on the current (non-Priority) channel, pressing the PTT button once causes the radio to switch to the Priority channel and cancels Dual Watch. Press the PTT button again to transmit on the Priority channel.

When a signal is received on the Priority channel, reception immediately shifts to the Priority channel, the DW icon will blink, and the display will become illuminated unless the Scan Lamp Feature is turned off. While receiving on the priority channel, if you momentarily press the PTT switch, Priority Dual Watch will be disabled. You may then transmit on the Priority Channel.

To stop Priority Dual Watch, press [F] [SCAN(DW)]. display. VOR Navigation To Select the DVOR Mode

When entering the NAV band (108.000 - 117.975 MHz), the VXA-300 selects the DVOR mode automatically. The Course Indicator field will appear at the upper left corner on the display, and the TO or FROM indicator will appear below the Course Indicator field on the display. Note: The Course Indicator indicates - - - when either your aircraft is too far away from the VOR station or the frequency is not correctly set to that of the VOR station. Conversely, the Course Indicator will indicate Loc when a localizer signal is being received.

The TO or FROM flag indicators indicate whether the VOR navigation information is 13/21 Vertex Standard Co., Ltd. FCC ID: K6610573X20 IC ID: 511B-10573X20 Operating Manual based on a course leading to the VOR station or leading away from the VOR station.
