The battery in your Remote is not replaceable. Do not attempt to
replace the battery.
The Remote is designed to the following temperature ranges:
• Operating: -20°C to +60°C (-4°F to 140°F),
humidity < 95% non-condensing
• Storage: -40°C to +60°C (-40°F to 140°F)
We are required by regulations to provide the following
warnings:
WARNING:
Use of the Remote directly next to other
electronic equipment should be avoided because it could
result in improper performance. If such use is necessary, note
as to whether your hearing aids and the other equipment are
operating normally.
WARNING:
Use of accessories, components or replacement
parts other than those provided by the manufacturer of the
Remote could result in increased electromagnetic emissions
and decreased electromagnetic immunity and could result in
degradation of performance.
WARNING:
If Portable Radio Frequency communications
equipment is used closer than 30 cm (12 inches) from
your Remote, degradation of the performance of your
hearing aid could result. If this occurs, move away from the
communications equipment.
Wireless Technical Description
The Remote operates in the 2.4 - 2.4835 GHz band with a
maximum effected radiated power of 3dBm with transmission
modulation type of 1M06F1W. The receiver section of the radio
has a bandwidth of 2 MHz.
The Remote has been tested to, and has passed, the following
emissions and immunity tests:
• IEC 60601-1-2 radiated emissions requirements for a
Group 1 Class B device as stated in CISPR 11.
• RF radiated immunity at a field level of 10 V/m between
80 MHz and 2.7 GHz as well as higher field levels from
communications devices as stated in Table 9 of IEC
60601-1-2.
• Immunity to power frequency magnetic fields at a field
level of 30 A/m.
• Immunity to ESD levels of +/- 8 kV conducted discharge
and +/- 15 kV air discharge.
The Remote has a rating of IP 5X per IEC 60529. This means that
the Remote is protected from dust.
The Remote does not contain any user-serviceable parts. Do not
