12.1 Maintenance and battery replacement
The WR20 Handset and Basestation are sealed waterproof units.
To create and maintain their waterproof integrity they were
assembled in a controlled environment using special equipment.
The units are not user maintainable and under no circumstances
should they be opened. For battery replacement or other service
please contact your local authorised Simrad Service Agent.
12.2 Pairing the Basestation and Handset
The Basestation and Handset provided in the box come as paired
units. If for any reason it is necessary to pair a Handset to a
different Basestation or vice versa the procedure is as follows.
Step 1.
Use a pointed instrument to depress the light button on the
base of the WB20 Basestation for between 3 and 5 seconds.
Step 2.
On release the light will flash twice in 1 second then off for
1 second. If this does not happen, repeat from step 1.
Step 3.
Hold the WR20 Handset within reach of the Basestation,
enter the “Setup” and “Installation” menu and select
“Pair to WB20”.
When successfully paired the product list appears in full when the
P
RODUCT key is pressed on the WR20 Handset.
