If the beltpack ALTAIR WBP-212 remains turned on during a period of ten minutes
without connection to the base station (the base station is turned off, outside range, or the
beltpack is not registered to any base station), it will be turned off automatically to
conserve batteries.
3.1 HEADSET CONNECTION
A TINY Q-G and a standard XLR-4 connectors allows to connect a headset to the
beltpack. The headset impedance must be of 200 or higher (up to 2 K) and the
microphone may be dynamic or electret type.
For the electret microphone type it is necessary to enable the phantom power of 9
VDC with a key combination or with a MENU selection.
The next list shows the TINY Q-G and the XLR-4 pins correspondence:
HEADSET

0 V (MICROPHONE)
PIN 2

PIN 3
0 V (HEADPHONES)
PIN 4

NOTE: Headphones could be with a double or single muff. In case of using a double muff
headphone, the two speakers should be wired in parallel mode.
3.2 MIC ON/OFF/PUSH TO TALK SWITCH (TALK)
The MIC switch allows to
enable/disable the microphone, so that we are
able to speak with other units connected to the same intercom channel.
If the microphone is activated, its associated LED will light up and this icon, will
show in the display: ,and on the other hand, if it is disabled, its associated LED will
turn off and will not show the icon in the display.
The MIC switch has two operation modes. When this switch is pressed quickly the
microphone changes its state, if it was enabled, upon being pressed it gets disabled and
turns off the associated LED, and if it was disabled, upon being pressed gets enabled and
turns on the associated LED.
When the MIC switch is pressed and held, the unit will enter in the special function
PUSH TO TALK, this means that the microphone will be enabled until the switch is
released.
The unit provides a MIC-KILL (turns off the MIC) system, so that when the mic is
enabled it is possible to muted it by the MIC-KILL function of the base station ALTAIR
WBP-200 or a master station EF-200, connected to the base station. This MIC-KILL
system is compatible with other intercom systems of the market.
The state of the MIC (on/off), it is stored in the unit.
