2.3.6 LOW BATTERY INDICATION
When the battery voltage falls below a preset
level, the icon appears in the display. This
icon stays on until power is turned off. In addition, the
following low battery indications may be programmed
to occur:
• The amber BATT indicator on the top panel lights.
• A beep sounds once per minute in the standby mode.
• A beep sounds each time the PTT switch is pressed.
The battery should be recharged as soon as prac-
tical after a low battery indication appears. Refer to
Section 5 for more battery information. There is also a
battery saver function that can be enabled by program-
ming. This function uses the RSSI level to determine
when the site is very near and then automatically
switches to the low transmit power output level.
