AC IVA ING HE HEARING PRO EC OR / REPLACING BA ERIES (Appendix A fig. A)
LEVEL DEPENDEN FUNC ION ( Only applicable on some models )
The version with level dependent function requires 2 standard AA 1.5 V alkaline batteries. Do not use
rechargeable batteries, such as NiMH 1.2 V or NiCd 1.2 V, as they significantly reduce the operating
time.
To protect against moisture and dirt, the battery case is built into the ear cup that has no buttons. Follow
our instructions to install and replace the batteries (Appendix A fig. A).
•Start by sliding down the ear cup to the bottom of the yolk (Appendix A fig. A1).
•Remove the cushion by firmly pulling outwards, note the orientation of the shaped part (Appendix A
fig. A2). Now remove the insert.
•nsert the batteries in the battery case. Make sure that the + and – poles are in the right direction
(Appendix A fig. A3).
•Replace the insert and snap the cushion in place (Appendix A fig. A4).
Note! After replacing the batteries, ensure that the insert and cushion are correctly installed to prevent
leakage in the passive noise attenuation. Make sure to turn the cushion so that its shaped part is dow-
nwards.
BA ERY WARNING
When only 10–20 hours of the battery’s life span remain, you hear two tones, which are repeated every
half-hour until the batteries die.
BA ERY SAVE FUNC ION
To maximise battery life the radio is equipped with a special battery save function. f no control buttons
are pressed, the battery save function comes into effect after 2 hours and the radio is shut down. To res-
tart, press the on/off button (o) placed in the centre of the keyboard.
SOUND LEVEL LIMI A ION
The versions with level dependent function are equipped with external microphones ( Small microp-
hones mounted on both cups ) which detects the surrounding noise. The surrounding sound is repro-
duced in the speakers inside the cups.
The function is operated by an external on/off/volume switch
P function (Only applicable on some models ) (Fig. D)
For versions direct connected to communication radios there is a PTT button outside one cup (Fig D1).
This PTT operates the communication radio. Keep the PTT pushed down for transmitting. Release the
PTT for receving.
MAIN ENANCE
The outside of the cups and the cushions can be cleaned easily with soap and water. Ear muffs and in
particular cushions may deteriorate with use and should be examined at frequent intervals for cracking
and leakage, for example. The cushions are filled with foam and are replaceable. t is easy to replace
worn and damaged parts (fig. A4). Make sure that the shaped part of the cushion is turned downwards.
Use only hygiene kits designed for electronics and provided by the manufacturer, product number
60084. The hygiene kit should be replaced at least twice a year for standard use to ensure that the
noise attenuation function does not deteriorate. This product may be adversely affected by certain che-
mical substances. Further information should be sought from the manufacturer. Do not subject the hear-
ing protector to rough handling, which can damage the electronics.
The user must make sure that:
- the ear muff or combined ear muff/helmet is fitted, adjusted and maintained according to our instruc-
tions
- the ear muff or combined ear muff/helmet is worn at all times in noisy environments
- the ear muff or combined ear muff/helmet is regularly inspected for serviceability
If the above recommendations are not adhered to, the protection afforded by the ear muffs can be
severely impaired.
BASIC FAUL FINDING/ELEC RONIC MAIN ENANCE
f the electronic functions stops working, the correction may be very simple. Please check the following:
•Check that the contact between the contact/adapter and the external unit is established.
