Heath Zenith SL-6157 Troubleshooting, Chime does not sound, Chime false triggers to loud noises

Troubleshooting

Chime does not sound:

¥Red light on the transmitter does not light. Check polarity of batteries. Re- place the transmitter batteries.

¥Red light on the transmitter does light. Make sure the transmitter and the chime channels are the same (see page 5). Make sure the plug-in chime has power going to it.

Battery seems OK, but the chime does not work when installed:

¥Do not mount the transmitter on metal or near metal studs. This reduces the transmitter range. Use 1/4" to 1/2" (6 to 13 mm) wood shims to move the transmitter off the metal surface.

¥Attach the microphone directly to the existing chime case very near the ringing part (but not on it) of the existing chime.

¥Try locating chime closer to transmitter.

The range of the chime can vary with location, temperature, and battery condition.

Chime false triggers to loud noises:

The Extension Transmitter has special circuitry to reduce false triggers from most common household noises. The transmitter is designed to optimize its response to mid-frequency sound where most mechanical doorbells operate and to minimize response to extremely low or high frequency sounds. Also, the desired sound must be present continuously for at least 2 seconds. This design reduces the response to door slams, vibration, normal music and talking, etc. Loud continuous noises such as yelling children or very loud music may cause false triggering. When operating in a location with unusu- ally high ambient noise levels try the remedies below.

¥Turn the sensitivity control counterclockwise to reduce sensitivity.

¥Mount the microphone inside the existing chime as mentioned in step 4.
