GPH Series VHF Radio Operation

3.7 OTHER OPERATIONAL FEATURES
The BK Radio G Series is based on a microprocessor core that allows extra features and operational
characteristics to be programmed into the radio. Your dealer can help define the best operational settings
for your system and program them into the radio.
3.7.1 Scan Delay
Scan delay lets the radio receive a response to a transmission before scanning the other channels for
activity. If you find that your scanner is restarting before message replies are received, you can ask your
dealer to increase the scan delay time (0-7.5 seconds).
3.7.2 HI/LO Transmit Power
Each channel in the radio can be individually programmed to always transmit in
low-power mode, regardless of the position of the radio's top switch (or keypad
[FCN]
menu setting). If the programming for the channel allows high-power
transmissions, the power level can be selected with a top switch or the keypad
menu.
3.7.3 DTMF Encoding
Keypad-equipped radios can be programmed to enable DTMF (Dual Tone
Multiple Frequency) encoding. To send DTMF tones (similar to the tones used by
a standard push-button telephone):
1. Press and hold the PTT switch.
2. Press any of the keys on the keypad.
You will hear a sidetone.
The
[FCN]
,
[PRI]
,
[ENT]
, and
[CLR]
keys respond as DTMF tones A, B, C, and
D, respectively.
3.7.4 ANI Encoding
ANI encoding (Automatic Number Identification), if enabled, transmits a
sequence of DTMF tones each time you press the PTT switch. You will hear a
sidetone. Your dealer can program the ANI number to be sent.
If DTMF and ANI are both enabled, the ANI tone sequence is transmitted only
after the
[ENT]
key is pressed while the PTT switch is activated. You will hear a
sidetone.
3.7.5 Time-Out Timer
The transmit time-out timer limits the duration of calls and guards against
accidentally locking on the transmitter and tying up the radio system. Your dealer
can program the duration of the time-out timer (15-225 seconds, or disabled).
