WIRELESS SECURITY MEASURES
Wireless signal security is assured through device system design
that includes:
• A built-in pairing table which specifies valid and legitimate
pairing among units.
• A proprietary Siemens communication protocol which checks the
package numbers during each transmission.
• A Cyclic Redundancy Check (CRC) to check data validity and
correct errors.
Push button on/off
Your Siemens hearing instruments may be programmed to
allow you to turn them on and off using the program button,
toggle switch, or rocker switch. To turn the instrument off
using the program button, press and hold the button for 3–5
seconds. To turn it back on, press and hold the program button
for 3–5 seconds. Please note that after having turned the
hearing instrument off using the program button, you must wait
approximately 10 seconds for the system to reset before turning it
back on again by using the program button.
Power on delay
Your hearing instruments may be equipped with an advanced
power-on delay feature. This feature delays sound from entering
your hearing instruments when they are first turned on so that
you may insert the
instruments into your ears without experiencing unpleasant
feedback (whistling).
Low battery indicator
Your hearing instrument may be programmed to inform you when
the battery should be replaced for best performance. You may hear
an intermittent series of beeps and/or experience low amplification
power or volume. Change the battery immediately if either of these
should occur.
Volume control alert tones
Your hearing instrument may be programmed to inform you
of changes to volume. You may hear soft beeps each time you
change the volume and a three beep warning when the volume
limit has been reached. Once the maximum or minimum volume
has been reached, further changes in that direction will have no
effect.
Program change alert tones
Your hearing instrument may be programmed to inform you of
changes to the program. The program change may be confirmed
by alert tones or beeps that correlate to the program you are in.
That means if you select Program 3, the hearing instrument will
beep 3 times.
