2.3 Register the Transmitter

The transmitter sends a check-in message to the receiver or gateway every 

60 minutes for the purposes of supervision. The transmitter must be 

registered and supervised.

Caution: 

The EN1221S-60 waterproof pendant must have a supervision 

window of no more than 12 hours to avoid not discovering a missing device 

within 24 hours.

Each transmitter has a unique factory-programmed identification number. 

Refer to the receiver or gateway's installation instructions for details on 

registering and setting up supervision.

6.

When prompted by the receiver or gateway to reset transmitter, press 

the activation button, and then clear the alarm per section 3.2, “Clear an 

Alarm”.

Caution: 

The transmitter should be tested after registration to ensure 

operation. See section 6, “Test the Transmitter”.

2.4 Wear the Transmitter

The pendant transmitter can be worn in three ways:

• Around the neck with the neck lanyard, which is included with the 

waterproof pendant with neck lanyard.

Caution: 

The neck lanyard included with the waterproof pendant is 

designed with a breakaway feature for user safety. Substitution of a 

stronger cord or chain may result in injury to the wearer.

• On the arm with the wristband, which comes attached on the

to fit wrist circumferences from 5.5 to 7.5 inches; the long wristband is 

designed to fit wrist circumferences from 6.5 to 9.25 inches.
