OPERATOR CONVENIENCES

APO (Auto Power OFF)

The transceiver switches OFF automatically if no keys or controls are pressed or adjusted, and no signal is received for 30 minutes (default). 1 minute before the transceiver switches OFF, warning beeps sound for a few seconds and “APO” blinks. Then, the transceiver turns OFF automatically. You can select the APO time from OFF (disable), 30 (default), and 60 minutes.

1Press [MNU].

2Turn the Tuning control or press []/ [] to select Menu No. 18 (APO).

3Press [] or [MNU].

4Turn the Tuning control or press []/ [] to select the APO time from OFF, 30, or 60 minutes.

5Press [] or [MNU] to store the setting. Otherwise, press [] or [PTT] to cancel.

Note:

The APO function does not work if the transceiver is scanning.

When Tone Alert is ON, APO does not turn the power OFF.

The APO timer starts counting down the time when no key presses, no control adjustments, and no command (SP/MIC jack) sequences are detected.

The APO warning beep sounds even if Menu No. 19 (KEY BEEP) {page 37} is selected “OFF”.

ATTENUATOR

The attenuator function is useful when extremely strong signals exist nearby your receiving frequency. When these type of signals are present, the receiver gain control may be erroneously controlled and overloaded by the strong signals, rather than by the target receiving signal. If this happens, the target receiving signal can be masked and buried by the strong signals. In this case, turn the Attenuator (approx. 20 dB) function ON. However, as a side effect, the target signal is also attenuated. You may have to adjust the VOL control to increase the audio output level when it is ON.

1 Press [F], [MONI].

“ATT ON” appears for 2 seconds on the display and the mode indicator starts blinking.

2To turn the attenuator function OFF, press [F], [MONI] again.

The mode indicator quits blinking.

Note:

When the attenuator function is ON, both A and B-band, are attenuated. You cannot set the attenuator function independently for each band.

“ATT ON” does not appear while scanning.

BATTERY LIFE

Before you operate the transceiver outside using a battery pack, it is important to know how long you can operate the transceiver. The following operating time is measured under the condition of TX: 6 seconds, RX: 6 seconds, and Stand-by: 48 seconds cycles. We recommend you carrying extra battery packs, in case the battery pack is discharged.

BATTERY REMAINING

You can confirm the remaining battery capacity using this function. Confirm the battery type {below} prior to use this function. To check the remaining capacity:

1 Press [F], [LOW].

The battery remaining indicator appears.

: High battery power

: Medium battery power

: Low battery power

: Needs recharging or replace the batteries

2Press [] or [MNU] to exit the Battery remaining display mode.

Note: If you press [F], [LOW] while charging, “CHARGE” or “STANDBY” appears {page 2}.

BATTERY TYPE

Before estimating the remaining battery capacity, set the battery type in Menu No. 30 (BATTERY) to the same type of battery that your are using (either Lithium or alkaline).

1Press [MNU].

2Turn the Tuning control or press []/ [] to select Menu No. 30 (BATTERY).

3Press [] or [MNU].

4Turn the Tuning control or press []/ [] to select the battery type from “LITHIUM” and “ALKALINE”.

5Press [] or [MNU] to store the setting. Otherwise, press [] or [PTT] to cancel.
