Notice SecurAccess PMR
3. The unit will start emitting "beep" tones during the reset
4. When the unit stops emitting "beep" tones, this means the reset is completed, the unit is back
to factory settings, including the programming code access (0000).
5. The unit will automatically hang up.

4. Special features

4.1. Shunt regulation

The unit is fitted with an automatic gain control system for plain old classical telephone lines.
In some cases, with very long lines or poorly powered lines (ATA, Operator modems, etc), the unit
may work poorly and it might be useful to shunt this regulation in order to recover more power and
ensure good working conditions. (See page 31).

4.2. Led lightning

The SecurAccess PMR comes with 1 or 2 off-hook buttons and one label display which can be
lighted. Buttons and label display backlighting require the use of the external power supply TRT3
24V DC/AC 1A (LPS) with double insulation (sold by Depaepe SAS) as well as the dedicated switch
activation.(see page 31,32).

4.3. Speaker overboost

In very noisy environments, receive sounds from the speaker can be amplified by 9 to 11 dB.
This feature requires an external power supply TRT3 24V DC/AC 1A (LPS) double insulation (sold
by Depaepe SAS) as well as the dedicated switch activation (see page 32/33).
(see page 31,32).

4.4. Heating resistor

The unit is fitted with a heating resistor useful for keeping it as dry as possible in very humid or (and)
cold conditions as well as with condensation conditions.
An external power supply TRT3 24 Volts DC or AC – 1A (LPS) with double insulation (sold by
Depaepe SAS) is needed to turn on the heat from the resistor, and the dedicated switch activation.
