ADL Vantage/ADL Vantage Pro/ADL Vantage 35
Antenna connector
The integrated antenna connector provides an industry standard TNC-female RF
connector that is compatible with a wide range of mobile whip antennas. Pacific Crest
also sells cables that connect the radio
to remote antennas.
Battery care
The ADL Vantage Battery/Charger kit includes a 12 V, 12-AHr, battery. The ADL Vantage
Pro Battery/ADL Vantage 35 Charger kit includes a 12 V, 35-AHr, battery. Both are
deep-cycle, deep-discharge, sealed lead-acid batteries, also known as portable power
batteries. Both batteries provide all-day operation for the respective radios and can
be recharged approximately 300 times over a period of three years if proper care is
maintained.
A deep-discharge battery will last longer if it is never fully discharged during use and
always fully charged before storage. If the battery is discharged entirely, the capacity
will diminish. The ADL Vantage Pro and ADL Vantage 35 radios will maintain the
transmit power level as the battery voltage is reduced. Transmitting at a high power
level for a long period of time may cause the battery to reach the automatic shut off
level before eight hours of use and will need to be recharged.
If you use your own battery, select a deep-discharge battery with a minimum capacity
of 30 AHr. If necessary, you can use an automotive battery, but it will be damaged by
repetitive discharge/charge cycles. An automotive battery will lose capacity in just a few
cycles. Pacific Crest does not recommend this practice.
To protect the battery from over-discharge, an ADL Vantage will flash a low voltage
warning when the input voltage declines to 10 V DC. If the voltage continues to decline,
the radio will shut itself off at 9 V DC. At 10 V DC, the LEDs on the front of the radio will
flash twice, pause, flash twice again, pause, etc. indicating low input voltage. If a radio
has shut itself off because of low input voltage, it will automatically turn itself back on
when the voltage returns to 9 V DC or higher.
The 10 V warning and 9 V shut-off levels are the factory defaults. If you wish, you can
use ADLCONF software (Radio Link - Advanced screen) to configure other power levels.
The minimum shut off level for an ADL Vantage Pro is 9 V DC and cannot be changed.
You can input a lower value for the ADL Vantage, but please be advised that
discharging a battery below 9V might permanently damage it.
Charging
The charger supplied with the radio Battery/Charger kit provides two-stage charging
and must be connected to the battery following every full day of operation to ensure
good battery life and performance. The first stage quickly charges the battery to
capacity, and the second stage trickle charges the battery to maintain a full charge. It
is important to recharge your battery every time it is used. Do not allow a battery to
remain in a discharged state any longer than necessary.
It is important to periodically charge any battery that is stored for an extended length
of time. Storing batteries for an extended time in a discharged state damages them
