3. Low Battery Threshold
Low Battery Threshold determines at what voltage level the LED will blink to indicate that the
battery voltage has fallen below the preprogrammed value in transmit mode. On the display
of your radio, you will see a battery flashing symbol. When aligning Low Battery Threshold,
you will not be able to test the voltage level until you reprogram the radio first. In order to
align this parameter, follow the steps below:
(a) Set up a battery block for the radio along with the Setup Procedure in Section VI-A, Fig. 8.
(b) Use the UP/DOWN arrow keys or PGUP/PGDN to increase/decrease these values. The
default value for this parameter is $9E which corresponds to 6.5 volts.
(c) Reprogram radio if finished with ALL alignment functions.
4. Battery Save Squelch
This adjustment is used to set the carrier squelch level at which the receiver will operate
when the radio is in battery save mode. Set the value to optimize battery save performance
for the particular system in which the radio will operate. When aligning Battery Save
Squelch, you will not be able to test the squelch level until you reprogram the radio first. In
order to align battery save squelch, follow the steps below:
(a) Follow the Setup Procedure in Section VI-A, Fig. 8.
(b) In order to align this parameter, you MUST be in Battery Save Squelch Mode which can
be done by first going into ALIGN CHANNEL and enabling the Battery Save Enable bit.
Return to ALIGN RADIO and reselect this alignment option.
(c) The Battery Save Squelch bytes contain the squelch level to be used while in battery
save mode. The default value for this byte can be determined as follows:
First find the minimum squelch among the channels defined for the radio and use this
value to index the following table to determine the value of Battery Save Squelch.
Minimum Squelch Level Battery Save Squelch Level
$00 $00 (minimum squelch)
$01 $01 l
$02 $02 l
$03 $03
$04 $03 l
$05 $03 --open squelch--
$06 $04
$07 $05
$08 $06
$09 $07
$0A $08
$0B $0A
$0C $0B
$0D $0C
$0E $0D
$0F $0E (maximum squelch)
