Introduction: The FM Tour Guide System is a portable, high-performance, wireless system composed of the PPA T16 Transmitter and PPA R7 Receivers and designed for use in hearing assistance applications. The system allows one-way transmission of a tour guide’s voice to hearing impaired group members by using an FM radio signal. Using the system helps to overcome background noise and distance from the person speaking.
MIC 036 Hearing Protector MIC 081, MIC 054 Lapel Clip MIC 026 Hand-Held Microphones: A noise-cancelling, headset microphone (MIC 044) is the standard microphone. The noise-cancelling microphone helps to reduce background sounds in noisy environments. The microphone plugs into the "MIC" jack on top of the Transmitter. The microphone is positioned directly in front of the tour guide's mouth for maximum signal to noise ratio and so head movement does not affect the loudness of the signal.
HED 008 Hearing Protector EAR 022 Surround Style EAR 014, EAR 013 Mini Earphone Headphones and Earphones: The HED 001 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 for cleaning or replacement. Replacement pads are part number HED 003-10. The headphone plugs into the "EAR/CHG" jack on top of the Receiver. The headphones are wired with a mono plug.
Operating Instructions: (Step 1) Install the battery in the Transmitter. A 9V alkaline battery is included with the transmitter. If you are using a 9 Volt rechargeable battery, see page 6. Open the battery door on the Transmitter by lifting the battery door up. A coin may be used to help open the battery door. Carefully insert the battery, observing proper polarity. The large battery terminal (-) is nearest the top of the compartment. DO NOT FORCE THE BATTERY IN BACKWARDS.
Hints for Using the System: Normal operating distance between the Transmitter and Receiver is about 100 feet (30m). 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 two feet apart.
Batteries and Chargers rechargeable "9V" batteries. The BAT 003 provides significantly longer battery life per charge than lower voltage batteries. Chargers: The BAT 005 Single Charger has a cord that plugs into the receiver "EAR/CHG" jack to charge the battery. The BAT 004 Charger has snaps for direct attachment of a 9V rechargeable battery. The CHG 1269 Multiple Charger can charge 12 receivers simultaneously through the receiver "EAR" jacks.
Instructions for the R7-4 Multi-Channel Receivers: The multi-channel Receivers have a rotary selector knob on top which allows the user to select any of four operating channels. The R7-4 tunes channels ACEG. These receivers are designed for use in multiple channel systems with a number of tour groups or language groups.
Setting the Transmitter Frequency: Selector Switches Transmitter Case Open Switches set for 72.9 UP (OFF) 1 2 3 4 5 6 7 8 DOWN (ON) Switches set for 72.9 MHz Channel A B C D E F G H I J Switch Settings (MHz) 1 2 3 4 5 6 7 8 72.1 72.3 72.5 72.7 72.9 75.5 75.7 75.9 74.7 75.
Receiver Frequency Change Instructions Tuning for the R7, R30, R31, and R32 receivers is determined by a single tuning coil. In the R7-4 and R7-6, one coil is assigned to each switch position. See the following 6 figures and receiver types to locate the coils to be adjusted. A plastic tuning wrench (PLT 005) will be needed to adjust these receiver tuning coils.
Step 5: Locate the Tuning Coil. (See figure on previous page). Each tuning coil is a small, square, shiny metal can with a screwdriver slot in a tuning slug in the top center. The Tuning Slug is usually black or gray. Step 6: With the earphone or headphone supplied with the receiver plugged into the Ear Jack, turn the volume control to a comfortable level, and lis ten for the transmitted signal. Step 7: Gently put the tip of the tuning wrench into the slot in the tuning slug.
