27 ADL Vantage/ADL Vantage Pro/ADL Vantage 35
Automatic Power Management
All ADL radios protect themselves from heat damage by shutting down if the temperature
inside the radio exceeds safe levels. Keeping the ambient (air) temperature below the
maximum operational temperature of 65°C (149°F) the best way to ensure that the
internal temperature of the radio does not exceed the save limits.
If an ADL radio does shut down in response to high temperature, wait until the radio
cools down and then turn it back on either by pressing the On button or by removing and
re-inserting the power/data cable. When the radio is turned back on after exceeding its
operational temperature maximum, it displays and Error 08 (high temperature) message.
To clear this message, power cycle the radio. If the storage temperature exceeds a level
that can damage the electronics the radio can continue to display the Error 08 and may
require repair.
The 35-Watt ADL Vantage Pro and ADL Vantage 35 radios generates more heat than
the 4-Watt ADL Vantage radio. For this reason, they include an Automatic Power
Management feature that reduces the transmit power before the radio’s internal
temperature reaches the 85°C maximum. The ADL Vantage Pro and ADL Vantage 35
will continue to transmit at reduced power until the internal temperature reaches 73°C
(163°F), whereupon the radio will automatically restore transmit power to the original
setting. If the Automatic Power Management feature is ever activated, the ADL Vantage
Pro and ADL Vantage 35 LCD will display an Error 08 (high temperature) message. Press
the Enter button to clear this message and then go to the radio’s Device Status screen to
display the current transmit power setting.
There are many ways you can reduce the temperature of your ADL radio besides reducing
the transmit power. Doubling the radio link rate halves the amount of heat generated by
the radio. Using a compressed data format such as CMRx can reduce the data packet size
by as much as 60% allowing the radio to generate 60% less heat. On hot days, keeping the
radio above the ground and out of direct sunlight can lower the temperature as much as
20°. When installing the ADL Vantage Pro and ADL Vantage 35 in a fixed location, you
should use the wall mount with fan accessory (P/N 82218-16).
