Replacement Part List

problem is the transmitter or the receiver.
One obvious thing to try is a different receiver, or a different transmitter, but
this is often not an available option if you don’t own a lot of equipment.
Replace the batteries in both before you go further.
An Ardy flushable transmitter can be tested by holding it near an AM radio
tuned to a dead spot (no station) on the dial. If the transmitter is working,
you’ll hear its raspy “beep-beep” from the radio.
A receiver can be tested in a rudimentary way by turning it up and holding it
near sources of electronic radiation-like a computer, a cell phone, a dimmer
switch. You should hear some noise. If it remains silent, the receiver is
probably malfunctioning.
We’ll play a 512 Hz tone over the phone, which you hold up to the receiver’s
antenna. If the receiver is working, the signal strength shown on the receiver
will be strong. Please note that this test cannot be done with a cell phone, it
must be an indoor land-line phone. Sadly, there is no phone test possible for
the receiver.
