Additional guidance
WARNING: Use of the Remote Microphone + 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
Microphone + 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
Microphone +, degradation of the performance of your hearing aid
could result. If this occurs, move away from the communications
equipment.
Although the Remote Microphone + is not formally certified (IP rated)
for protection against dust or water ingress, per IEC 60529, it has been
tested to the IP 5X level. This means that the Remote Microphone + is
protected from dust.
The battery in your Remote Microphone + is not replaceable. Do not
attempt to replace the battery. The Remote Microphone + does not
contain any user-serviceable parts. Do not open or modify it.
Do not connect the Remote Microphone + to any devices not
described in this manual.
The expected service life of the Remote Microphone + is 3 years.
Wireless Technical Description
Starkey Laboratories, Inc. Remote Microphone + operates in
the 2.4- 2.4835 GHz band with a maximum effective radiated power
of 8 dBm with transmission modulation type of 1M12FXD and 1.1 MHz
bandwidth. The receiver section of the radio has a bandwidth of
2 MHz.
The Remote Microphone + has been tested to, and has passed, the
following emissions and immunity tests:
• IEC 60601-1-2 radiated and conducted emissions requirements for
a Group 1 Class B device as stated in CISPR 11.
• Harmonic distortion and voltage fluctuations affecting the power
input source as stated in Table 2 of IEC 60601-1-2.
• 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 and proximity magnetic fields as stated in Table 11 of IEC
60601-1-2
• Immunity to ESD levels of +/- 8 kV conducted discharge and +/- 15
kV air discharge.
• Immunity to electrical fast transients on the power input at a level of
+/- 2 kV at a 100 Hz repetition rate.
• Immunity to surges on the power input of +/- 1 kV line to line.
• Immunity to conducted disturbances induced by RF fields on the
power input as stated in Table 6 of IEC 60601-1-2.
• Immunity to voltage dips and interruptions on the power input
as stated in Table 6 of IEC 60601-1-2.
