4.1 Batteries and Dip Switches
The WH31P probed thermometer requires 2 x AA batteries (not included). We recommend Energizer
Lithium batteries for longer life and a wider operating temperature range.
1. Remove the battery door on the back of the transmitter(s) by sliding down the battery door, as
shown in Figure 2 .
Figure 2
2. BEFORE inserting the batteries, locate the dip switches on the inside cover of the lid of the
transmitter.
3. Channel Number: The WS-2000 and WS-5000 supports up to eight transmitters. To set each
channel number (the default is Channel 1), change Dip Switches 1, 2 and 3, as referenced in
Figure 3.
