REAR PANEL INPUTS

2 1

The rear panel has three (3) inputs:

1. DC in. This is the main power in connector. Use only a power supply provided by

AWS, Inc., Part No. DCPA-110. Using the wrong voltage or reverse polarity will cause
damage to the system.

2. RS-232 connector.

3. Transducer Input: Plug the transducer into this 12 pin circular connector. This is a

PUSH LOCK, not a Twist connector. All transducer power, signal and Intellect
communications are input through this connector.

CHARGING THE BATTERIES

1. The batteries in this system should last approximately 12 hours when fully charged.
The Low-Battery indicator on the display will illuminate when the battery voltage is
low. Typically, the user will have between 15-30 minutes before the batteries
become too weak to power the unit.

2. The batteries are charged any time the system is plugged-in. In Fast Charge mode,
i.e. the unit is plugged in and the power is
depending on battery charge level. The green LED on the front panel will flash when
the battery is charging and turned off

Note: If the tester is to be stored for several months, always ensure the battery is

completely charged prior to storage. It is recommended the tester be plugged in
when not in use. This will not harm the unit and will increase battery life.

OFF, charge time is between 2 and 4 hours
