27 ADL Vantage/ADL Vantage Pro/ADL Vantage 35
Automatic Power Management
All ADL radios protect themselves from heat damage by throttling back the output
power or by shutting down if the temperature inside the radio exceeds safe levels. Not
operating the radio in environments greater than the maximum operational temperature
(see section on Technical Specifications) is the best way to ensure that the internal
temperature of the radio does not exceed safe limits.
If an ADL radio shuts down in response to high temperature, wait until the radio cools
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 an 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 generate 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 maximum level. The radios will continue to transmit at reduced
power until the internal temperature reaches a safe level, whereupon the radio will
automatically restore transmit power to the original setting. If the Automatic Power
Management feature is 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 indoor location,
you should use the wall mount with fan accessory (P/N 82218-16).
