Power Level; Scan; Starting/Stopping Scan; Talkback - Motorola GP140 User Manual

Power Level

You can transmit your calls at different transmit
power levels. A higher level means you can reach a
radio that is farther away. Lower power level
conserves battery power. You are advised to
transmit as frequently as possible on low power, and
use high power only when needed.
Press the programmed Tx Power button to toggle
between the options for High or Low power transmit
level. A positive indicator tone indicates that the
radio is operating in low power mode, while a
negative indicator tone indicates that the radio is
operating in high power mode.

SCAN

You can monitor several channels in order to receive
any call that is transmitted on any of these channels.
Sixteen different channels can be programmed into
a scan list. Each channel can share the same scan
list or have different scan lists assigned to them.
Once the radio's scan operation is activated and the
radio detects a call coming through a channel in its
scan list, it switches to that channel for you to
receive the call.
Starting or Stopping a Scan Operation
The LED Indicator will blink (green) during a scan
operation. It will stop blinking when the radio
switches to a channel.
1. Press the Scan key to start a scan operation.
2. Press the Scan key again to stop the scan
operation.

Talkback

If the programmable Talkback option is set, you can
respond to any calls received during the scan
operation by pressing the PTT before the
programmed hang-time ends. Check with your
dealer for details.
