Telephone Will Not Hang Up
In order to reduce the number of moving parts, subject to wear or damage, Guardian telephones are equipped with a magnetic reed hook switch.
a. Model EXT-401
The EXT-401 contains a magnet midway between the ear and mouthpiece of the hand set. If the phone will not hang up, be sure the handset is fully in place on the cradle.
On occasion the hook switch may jam; passing a magnet across the top of the handset cradle should correct the problem. If the problem persists, follow the Return Materials Authorization procedure.
b. Other Models
Other Guardian models, such as the WRT, SCT and WTT series contain magnets in the handset ear piece. If the handset is fully in place in the cradle and the phone remains off-hook, pass a magnet through the cradle. The hook switch should reset.
It is possible for the problem to be corrected and reoccur. Should this happen, the ear piece may be defective and should be returned following the Return Materials Authorization procedure.
