• Error Codes 15-16: If you are using the radio as a repeater, make sure that the transmit and receive
frequencies are less than 10 MHz apart. Otherwise, you should return the radio for service. If the radio
displays Error Code 15 (Transmit frequency lock error), it is important to stop using it because the crystal
oscillator might be unstable and you might be transmi ng at an unprogrammed frequency for which you are
not licensed.
• Error Code 17: If data comes into the radio faster than it can be transmi ed, the serial buff er can overfl ow.
If the radio displays Error Code 17, you should adjust the serial baud rate and radio link rate so the radio has
enough me to transmit each data packet before the next packet is sent to the radio.
If the radio con nues to display the error code a er you have fi xed the situa on, you may clear the error code from the
radio’s display by pressing the On/Off bu on for 3 seconds (turning off the radio), wai ng one full second and pressing
the On/Off bu on a second me. If an error warning persists, contact a Pacifi c Crest authorized dealer or

RF Output Power Regula on
Excessive heat is the enemy of all electronic equipment. For this reason ADL radios are equipped with RF (Radio Frequen-
cy) output power regula on fi rmware. Both the ADL Vantage and ADL Vantage Pro radios can operate safely with an am-
bient temperature as high as 65 degrees [use the degree symbol] cen grade (150 degrees Fahrenheit). But if the radio
detects an internal temperature rising close to the maximum, it will reduce its RF output power automa cally. While this
reduces range temporarily, it also prevents damage to the radio that might cause a permanent loss of range.
If the ADL Vantage senses its internal temperature approaching the limit while it is set to transmit at its maximum 4
Wa s, the radio will reduce its output power to 2 Wa s. If the temperature con nues to rise at the 2 Wa se ng, the
radio will turn off its transmi er completely. The radio will stay on and will display a “High Temp” message on its LCD
screen. When the internal temperature decreases suffi ciently, the RF output power will automa cally increase. Any
automa c change in the power se ng - either a decrease or an increase - is preceded by a message sent to the receiver
radio(s) informing them of the change. Other ADL Vantage or ADL Vantage Pro radios will display this message to the
user on their LCD displays and by fl ashing all three LEDs for 5 seconds.
If the ADL Vantage Pro senses the internal temperature approaches the limit while it is set to transmit at its High transmit
power (as programmed into the radio with ADLCONF confi gura on so ware), the radio will reduce its output power by 5
Wa s. If the temperature con nues to rise, the radio will reduce its output power by another 5-Wa s and so on un l the
Medium transmit power level is met. The radio may then reset itself to output at the 2 Wa Low power se ng or shut
off the transmi er. As with the ADL Vantage, RF power output will automa cally increase as the radio’s internal tem-
perature decreases.
If for some reason the ADL Vantage/ADL Vantage Pro radio’s internal temperature is ever exceeded, it will automa cally
shut off the transmi er and display the Error 08 (excessive internal temperature). Shut the radio off , let it cool and turn
it back on. If the storage temperature maximum has been exceeded, the radio will con nue to display the Error 08 and
may require repair.
