level.
7 Place the MODE switch in the IDENT position.
8 Adjust R22 CW until the meter deflects between 5.5 and 12V during ident.
Note:
Check that meter continues to deflect after adjustment tool is removed.
Note:
An analog meter or oscilloscope is easier to read than a digital meter for this
adjustment.
4.8.6 Automatice Shutdown Test
To check the automatic shutdown feature for ident failure, place the MODE switch in CONT.
After a delay of 15 to 60 seconds, the transmitter will shut down. Reset the system. To check for
