2.1. OPERATION

All tests should be performed in the order shown below. If the beacon has been operated before

checking the battery voltage, the beacon must be allowed to rest for at least 1 hour. No matter how

long the beacon has been operated, this rest period will ensure that an accurate measurement of the

battery voltage is observed.

A. Turn the test set ON using the small slide switch located on the left side of the housing.

B. If the display reads LB, LO BAT or ∆ on the left side, the TS500 battery voltage has fallen be-

low the level required for operation of the test set and the 9 Volt battery should be replaced.

See Maintenance Section 3.2.

C. Testing Beacon Voltage. Choose the appropriate cable for the beacon (large clip for the

DK180 (8.8 kHz) and smaller clip for the DK100 series (37.5k Hz)). Attach the test probe clip

to the beacon case. See Figure 2. Place the tip of the probe in contact with the silver pad on

the white dome at the end of the beacon. The display will show the battery voltage of the bea-

con. Refer to the appropriate beacon manual for the acceptable range of the beacon battery

voltage.

D. Operational Test. Place the probes on the beacon as described above and press the red button

on the TS500 (the test set display will be blank during this operation). The beacon should acti-

vate and a sound will be audible from the TS500. It is not necessary to operate the beacon for

more than 30 seconds during the operational test. Please note that high levels of background

noise can interfere with this test. If difficulty is experienced in hearing the beacon, the operator

should repeat the test in a quieter area.

The TS500 LED Indicator will also illuminate when the beacon is actively pinging. The LED

Indicator will illuminate "RED" for each 37.5

kHz ping and "GREEN" for each 8.8 kHz ping.

Note: A new DK180 will transmit once every

second during the first 10 minutes of operation.

After the first 10 minutes, the DK180 will trans-

mit once every 10 seconds. It is not necessary to

operate the beacon for the initial 10 minute peri-

od before installation.
