PSA-65C USER FAMILIARIZATION
AND
PRELIMINARY CHECKOUT
It is very important that the spectrum analyzer is not stored in freezing temperatures.
Operation can also be affected by cold or freezing temperatures. Cold battery capacity
is lower, perhaps only 30% capacity available.
When operating in battery mode, turn off the spectrum analyzer when battery voltage
falls to 11.4 volts (as read with Battery Monitor switch), not doing so will decrease
capacity.
BATTERY PACK CHARGING/CARE
IMPORTANT - Charge battery a minimum of three hours before operation on battery. 80% or
more charge will occur after six hours of charge.
1. Place POWER switch into STBY position.
2. Plug PSA-65C into a grounded outlet of correct voltage.
NOTE: Amber STBY LED is illuminated.
3. Set INT/EXT switch on rear panel to "INT", for INTernal.
4. Turn BAT CHG to "ON" position.
NOTE: Amber LED is illuminated.
5. Recharging time will vary depending on the discharge state of the battery. A fully dis-
charged battery will recharge in 8 hours.
NOTE: An external set of 12 volt batteries may be recharged via the DC jack. Output of the
DC jack is about 1/2 amp at 13 to 15 volts when the internal charger is on in the EXT
position.
BATTERY RECHARGING OR OPERATING FROM AN EXTERNAL CHARGING
SOURCE.
1. Plug the DC AUTO adapter cable into the DC Input Jack.
2. Set INT/EXT switch on rear panel to "EXT".
3. Connection to car adapter should only be made with car engine running.
4. Plug the DC AUTO adapter cable into the car's 12 volt socket.
NOTE: Recharging current can be as high as 4 amps at 13 to 15 volts. Keep a few spare 4
amp fuses for the adapter or analyzer with you in case of need. The spectrum ana
lyzer can be operated off any external DC source (center pin positive) between 11.5
and 15 volts DC.
