Using the R16 with a Hearing Aid:
Plug the optional NKL 001 Neckloop into the EAR jack instead of an earphone. The Neckloop creates a magnetic
signal that can be picked up by a hearing aid equipped with a T-Coil. Turn the hearing aid switch to the "T"
position and adjust the hearing aid and receiver volume controls for the best level.
Battery Information for Receivers:
Use only an alkaline 9 Volt disposable battery (BAT 006) or a 7-cell rechargeable 9 Volt battery
(BAT 003) with the PFM R16/R16M. The BAT 003 rechargeable battery must be used with a BAT 004, BAT 005,
orCHG 1269A Charger. Other batteries and chargers are NOT recommended. Donot mix rechargeable batteries
and chargers from different manufacturers. Poor battery life or failure can result.
In normal use, an alkaline battery such as the Eveready 522 will provide about 17 hours of use. If the sound
becomes weak or distorted, replace the battery. The indicator light may still be on, even with a battery that is
weak. Do not leave dead batteries in the receivers.
Rechargeable Batteries:
For the 9V R16, we recommend only the 7-cell, 8.4 Volt types (Williams BAT 003). A fully-charged BAT 003 will
provide about 5 hours of use per charge. The battery may be recharged without removing it from the receiver.
The R16-72E6 has a built-in6V rechargeable battery pack (BAT 021) that will operate for approximately 15 hours
per charge. The BAT 021 Battery Pack can be replaced when it no longer holds a charge.
The BAT 005 Single Charger is used with 6V and 9V receivers andhas a cord that plugs into the receiver "EAR"
jack to charge the battery. It takes about 14 hours to fully charge the battery. If the BAT 005 Single Charger is
used, the receiver can be left charging continuously when not in use. The optional CHG 1269A Multiple Charger
can charge 12 receivers simultaneously through the receiver "EAR" jacks. The receiver should always be turned
OFF while charging.
DO NOT ATTEMPT TO RECHARGE DISPOSABLE BATTERIES!
AVOID SHORTING THE PLUS AND MINUS BATTERY TERMINALS TOGETHER WITH METAL OBJECTS.
BATTERY DAMAGE AND BURNS CAN RESULT!
DO NOT MIX RECHARGEABLE BATTERIES AND CHARGERS FROM DIFFERENT MANUFACTURERS.
Receiver Tone Controls:
The R16 and R16M have internal adjustments to cut low frequency sounds and to boost high frequency sounds.
The adjustments are made by moving jumpers inside the receiver.
(1) To open the Receiver, first flip open the battery compartment door. The back of the receiver opens like a
book - pull up and out on the battery door to open the back.
(2) Look at the receiver layout guide below to identify the jumpers. Don't "adjust" anything but the jumpers!
(3) The jumpers are moved by lifting them straight up. Placing the jumper across both posts sets it in the ON
position. Placing the jumper on only one of the posts sets it in the OFF position. Each jumper has the effect
shown in the chart below. The jumpers can be used individually or combined to alter the frequency response of
the receiver. For example, using Jumpers 2 and 3 in the ON position provides 12dB of boost at 8kHz. The
jumpers affect both the FM and environmental microphone signal. Receivers are sent from the factory with
Jumper 1 on and Jumpers 2 and 3 off.
R16 Layout Guide - Tone Controls
Jumper 1: Low Frequency Boost (-10 dB at 100 Hz)
when jumper is on.
(-25dB at 100Hz when jumper is off)
Jumper 2: High Frequency Boost (+6dB at 8kHz)
when jumper is on.
Jumper 3: High Frequency Boost (+6dB at 8kHz)
when jumper is on.
