4.0 OPERATIONAL USE
4.1 The Switch
A rotary switch is mounted in the release end cap (see Figure 4-1). An engraved arrowhead marks the
switch position. There are three positions:
a.
HOLD-EXTEND. Here the 865-A is OFF. When switched to this position, the pin will extend
if it is not already extended. Store the unit with the switch in this position.
IMPORTANT : When switching to HOLD-EXTEND, be sure that the lever is off
to one side so that the pin will not jam into the end of the lever. If this does
happen, the fuse will blow.
b.
ON-ARMED. Here the 865-A is ON. This is the position the switch MUST be in when the unit
is deployed. The 865-A will ping four times to let you know it has powered-up successfully.
c.
TEST-RETRACT. Here the 865-A is ON and the pin will retract. Use this position when
reloading an expendable link. Note that a four-ping burst occurs when the pin is fully retracted.
4.2 Testing
It is always a good idea to test any instrument on deck prior to deployment. To test the 865-A, simply
follow these steps:
4.2.1 Power On
Using a coin or screwdriver, turn the switch to the ON-ARMED position. The release will signal to you
that it has powered up successfully by transmitting four pings.
4.2.2 Single Transpond
a.
Place your deck unit transducer near the 865-A transducer. Set the TRANSMIT
FREQUENCY (Tx) to the receive frequency of the 865-A and the RECEIVE FREQUENCY
