The Dual Channel Manager Beltpack WBP-202 unit was designed for intensive use in portable
applications. An unbreakable plastic belt clip enables easy and secure suitability. Call signalling is
Triple, visual, audible and with a vibration for improving adaptability. The unit can be configured for
dynamic or electret microphones enabling the use of different types of headsets and hands-free
earpieces in the market.
This beltpack is designed for operation under the new Altair WBS-202 dual channel base station
in order to obtain full operation functionalities.
A maximum number of 1 WBP-202 unit per Radio 1 and another unit per Radio 2 is allowed.
The WBP-202 is provided with an ON/OFF switch, a CALL switch, a MIC on/off switch, BUZZER on/
off switch, headphones volume control, etc...
In order to begin to use its new beltpack ALTAIR WBP-202, first turn on the base station on which
the beltpack is registered (if it is not registered to any base, goes to the registry section).
Once turn on the base station, push the on/off switch of the beltpack. All the beltpack
leds light on and last a little while it will sound the buzzer (if buzzer is turn on) and will vibrate
(if the vibrator is turn on), indicating that it is operative.
If the base on which it is registered finds within its range, the LED of IN RANGE
will begin to blink and the audio will be opened. At this moment you can begin to use your
beltpack ALTAIR WBP-202.
If the beltpack ALTAIR WBP-202 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.
HEADSET CONNECTION
A TINY Q-G type connector allows to connect a headset and a microphone to the beltpack. The
headset impedance must be of 200 Ωor higher (up to 2 KΩ) and the microphone may be dynamic or
electret type.
For the electret microphone type is necessary to enable the phantom power of 9 VDC with an
internal preset. In order to obtain more information, consult the special operation section.
The next list shows the XLR pins correspondence:
HEADSET
PIN 1 0 V (MICROPHONE)
PIN 2 SIGNAL (MICROPHONE)
PIN 3 0 V (HEADPHONES)
PIN 4 SIGNAL (HEADPHONES)
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.
CHANNEL SELECTION SWITCH
The main function of this switch is to select the operation channel you want to
communicate. Selected channel is indicated on the indicator lamps A and B. The
selection is circular: A-AB-B-AB-A-AB-B… so, by pressing this switch, the selection changes to the
opposite channel with intermediate positions AB between them. Channel selection affects the
beltpack functions as described:
MIC: The beltpack mic signal is feed to the selected channel indicated by the lamps. You can adjust
your mic level by pressing the mic switch and change its gain with the up-down arrows.

LISTENING The listening channel depends also of the selected channel indicated by the
lamps. By selecting AB, you can listen both channels simultaneously. A balance listening
between channels is allowed in each of the 3 possible selections A, AB and B. By using this
balance, you can listening the opposite channel at a small, say 20 % level, helping
management of both channel crews at a time.
CALL The sending Call channel is the indicated on the lamps. When AB is selected, a Call is
sent to both channels. The receiving channel Call is also shown on the AB lamps by flashing
accordingly. As the selected channel is obviously not automated, you must go to that
channel if you are in the opposite channel in order to communicate with him.
CHANNEL LISTENING BALANCE
You can adjust the listening balance between channels A and B in all the 3 possible selections:
A Selected channel: Holding down the Channel select switch, change
the balance with the up-down arrow switches. Balance is shown by
the percentage of time the A and B lamps are illuminated.
Factory preset: Listen channel A only, corresponding to many flashes to A, nothing to B.
B Selected channel: Holding down the Channel select switch, change
the balance with the up-down arrow switches. Balance is shown by
the percentage of time the A and B lamps are illuminated.
Factory preset: Listen channel B only, corresponding to many flashes to B, nothing to A.
AB Selected channel: Holding down the Channel select switch, change
the balance with the up-down arrow switches. Balance is shown by
the percentage of time the A and B lamps are illuminated.
This balance can be useful to balance channel power in some special circumstances:
As an example sound crew will talk louder than video crew as the environment is noisy.
Factory preset: Listen bothchannels A+B, corresponding to some flashes to A, and B.
STAGE ANOUNCE (SA) KEY
With this function, you can send a message to the PA (Public Address) system
from your beltpack at any time.
Press and hold the Channel Select switch and when the AB lamps flashes (wait 2
seconds), start your message from the headset microphone. When done, release the switch.
On the WBS-202 base station, the front panel SA led will glow for the time you are depressing
this switch and the message is carried out from the SA output to the external PA equipment. This
function is very useful for timing events, fire alarms, or general announces.
Intercom mic signal is not interrupted in this mode and remains in the selected channel.
CALL SWITCH
When this switch is pressed, a call signal is sent to the system and to the
intercom channel in which it is connected the base station. The call signal makes the LED
associated with the switch to start blinking; if the vibrator is enabled (see vibrator on/off
section for more information) will be vibrate; if the buzzer is enabled (see
buzzer on/off section for more information) an intermittent sound takes place during about three
seconds, the same as in all the units (wireless beltpacks, beltpacks, base stations, desk stations,
master stations, etc.), connected to the same intercom channel.

The IN RANGE led of the base station correspondent to the register number of the beltpack will
be blink. In the wireless beltpacks will be turn on the associated led with the wireless beltpack that it
is calling (LOW BAT — 1, BUZZ ON/OFF — 2, MIC ON/OFF — 3, IN RANGE — 4). If the call is generated by
the base station, all associated led will be turn off.
If the CALL switch is pressed continuously, the duration of the call signal will be higher (the time
that the switch is pressed and approximately 3 second more).
If a call signal is generated in an external unit (wireless beltpacks, beltpacks, base stations,
desk stations, master stations, etc.), the LED associated with the CALL switch will start blinking, if the
vibrator is enabled (see vibrator on/off section for more information) will be vibrate, and if the buzzer
is enabled (see buzzer on/off section for more information) an intermittent sound will take place
during about three seconds.
As depicted on Channel selection paragraph, the incoming channel Call is shown by the AB
lamps.
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 on
the other hand, if it is disabled, its associated LED will turn off.
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-202 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.
BUZZER ON/OFF SWITCH
This switch enables/disables the buzzer sound when the unit receives a call
and when the user presses a key. Whenever this switch is pressed, and the buzzer is
enabled, it will be disabled, and the LED indicator will turn off. On the other hand, if
the buzzer was disabled, it will be enabled and the LED indicator will lighten up.
The buzzer also sounds when any switch is pressed, emitting a short hoot, when it is enabled.
The unit provides a BUZZER-KILL (turns off the BUZZER) system, so that when the buzzer is
enabled it is possible to muted it by the BUZZER-KILL function of the base station ALTAIR WBP-202 or a
master station ALTAIR EF-200, connected to the base station. This is a proprietary BUZZER-KILL
system, so it is not compatible with other intercom systems on the market
The BUZZER could be disabled with an internal preset. In order to obtain more information,
consult the special operation section.
The state of the BUZZER (on/off), it is stored in the unit.
VOLUME UP/DOWN SWITCH

beltpack leds light on and last a little while it will sound the buzzer (if buzzer is turn on) and
will vibrate (if the vibrator is turn on), indicating that it is operative.
If the base on which it is registered finds within its range, the LED of IN RANGE
will begin to blink and the audio will be opened. At this moment you can begin to use your
beltpack. .
To turn off the beltpack, press and hold two seconds the ON/OFF switch when the beltpack is
turned on. In this moment will sound the buzzer (if the buzzer is turn on) and when the ON/OFF switch
it is depressed, the beltpack it is turned off.
If the ON/OFF switch it is short pressed, the beltpack will show us the battery status (LOW BAT led
— 10%, BUZZ ON/OFF led — 40%, MIC ON/OFF led — 70% and IN RANGE led — 100%).
IN RANGE LED
The IN RANGE led when blinks indicates that the beltpack is in the station base
range, if it is turn on without blinking, indicates that the beltpack is not in the station
base range or the base is off.
LOW BATTERY LED
The low battery LED starts to blink when the battery is discharged by 90%,
indicating that we should charge the battery as soon as possible, if we want to
continue using the beltpack.
VIBRATOR ON/OFF

DC-IN CONNECTOR
The three NiMh, AAA, 1000 mA/h batteries of the wireless beltpack must be charged with the
ALTAIR WBPC-200 charger by the DC-IN connector. The polarity is tip positive.
Charging time is three hours with the batteries empty. After this 2-3 hours time, the charger sets
to trickle (maintenance) mode and can be left alone in the charger. For a full charge, it is
recommended a 2 hours minimum charging in this state.
The estimated battery life, in full duplex mode is 10 hours and 50 hours in standby mode, with
full charged batteries.
The included NiMh batteries has a shelf discharging time around 2 to 4 month. So it is
imperative to check the battery status before use: switch ON the unit and then, press shortly the ON
switch . As a general rule, charge the unit before using the system.
4. SPECIAL OPERATIONS
