This LED will blink once every two seconds when the handheld unit is unable to find a ScoreLink server. It will illuminate briefly when the device powers up fully.

Batteries

The Play Clock Switch Assembly requires two AA batteries to power it for wireless operation. These can be standard alkaline batteries or rechargeable batteries. Either style should provide over 20 hours of operation on a fresh charge. You cannot recharge batteries inside the handheld unit.

Electro-Mech's wireless switch assemblies are designed to conserve battery power when they are not active. The units drop into a lower power mode when they are unable to detect the presence of a ScoreLink server for several minutes. You can manually activate this low power feature by holding the [MODE] button for about five seconds. However, the internal electronics continue to drain the batteries slightly. We recommend removing the batteries if the units will not be used for a few days.
