SYSTEM OVERVIEW The Hearing Helper® Tour Guide System is a portable, high-performance, wireless system composed of a transmitter and receivers and designed for use in guided tour applications. The system allows one-way transmission of a tour guide’s voice to group members using an FM radio signal. Using the system helps group members overcome background noise and distance from the person speaking. The Hearing Helper® System can be used for large or small tour groups and in noisy or quiet environments.
SYSTEM COMPONENTS Body Pack Transmitter with (2) AA batteries (BAT 001) Noise-cancelling headset microphone (MIC 044) (6) Personal FM Receivers w/batteries (BAT 001) and headphones (HED 021) (7) Belt clip cases (CCS 001) Instruction Manual (MAN 106) System carry case (CCS 030 S) THE TRANSMITTER The transmitter is a battery-powered body-pack model used with a microphone to pick up the tour guide's voice.
HEADPHONES AND EARPHONES The HED 021 Lightweight Headphone is the standard headset for the Tour Guide System. It offers excellent sound quality and wearing comfort. The foam earpads may be removed and washed in a mild detergent, rinsed thoroughly, and air dried. Replacement pads are part number HED 013. The headphone plugs into the “EAR” jack on top of the Receiver. The headphones are wired with a mono plug. If a stereo headphone is substituted, it will only work on one side of the headphone.
OPERATING INSTRUCTIONS USING THE TRANSMITTER Note: Rechargeable batteries are shipped in a discharged state and must be charged overnight before using. 1. Make sure there are two charged AA batteries in the transmitter. If batteries are not installed, see Battery Information on page 10. 2. Plug the microphone cord into the “Mic” jack on top of the transmitter. 3. Place the transmitter in the belt clip case provided. FIG.
USING THE RECEIVER Note: Rechargeable batteries are shipped in a discharged state and must be charged overnight before using. 1. Make sure there are two charged AA batteries in the Receiver. If batteries are not installed, see Battery Information on page 10. 2. Plug the earphone or headphone into the “Ear” jack on top of the Receiver.

HINTS FOR USING THE SYSTEM Normal operating distance between the transmitter and receiver is about 30 meters. The operating range will vary in different buildings and surroundings. In some locations, the signal may momentarily disappear. This is called a “drop-out” and is due to reflection and cancellation of the radio signal. Moving a few feet will restore the signal. Keep the transmitter and receiver units at least a meter apart.
BATTERY INFORMATION INSTALLATION Open the battery compartment using a coin in the slot in the bottom of the receiver or transmitter. Press the batteries into place, observing proper battery polarity. Incorrect insertion of the battery is difficult, and if forced, may cause both mechanical and electrical damage to transmitters or receivers not covered by the five year warranty. Units will not work with the battery incorrectly installed.
periods of use, 1-2 hours, will shorten battery life (NiMH batteries do not have this characteristic). Rechargeable batteries will need to be replaced after 1-2 years of use. Do not dispose of batteries in fire. Do not open batteries, there are toxic chemicals inside. USING THE OPTIONAL CHG 1600 BATTERY CHARGER With AC power connected, the CHG 1600 Multiple Charger operates in a “trickle charge” mode. Units can be left on trickle charge indefinitely without risk.
IN CASE OF DIFFICULTY If your Tour Guide System is not working, check the following: 1. Make sure the batteries are fresh or completely charged and that the “plus” and “minus” terminals are installed correctly. 2. If the rechargeable batteries will only work for a short period of time (less than 1 hour) even after they are fully charged, they must be regenerated. Leave them in the receiver or transmitter with the unit turned on, for 5 - 6 hours.

Williams Sound warrants it against defects in materials and workmanship for FIVE (5) years EXCEPT FOR earphones, headphones, rechargeable batteries, chargers, cables, antennas, carry cases, and all other accessory products.
