Operating Instructions
8 Operation
8.1 Start Stop talking
The console device has a “PTT” (push to talk) utton. Push this utton to talk to the other station. You can either
talk permanently or temporarily. Push the utton riefly and release it (< 250 ms) to activate the permanent
mode. You do not need to hold or operate any controls while talking in this mode. Push riefly (< 250 ms) to
deactivate the mode again. If you push and hold the utton (> 250 ms), you activate the temporary mode. In this
mode, you can talk as long as you hold down the utton. Releasing it deactivates the temporary mode instantly.
The mo ile device has a “Mic” switch utton. Switch or push this utton to talk to the other station. You can either
talk permanently or temporarily. Switch the utton to "On" to talk permanently. The utton stays in this position
and allows you to talk to the other station until you switch the utton ack to "Off“. Push the utton to "(On)" to
talk temporarily. You can talk as long as you hold the utton in this position. The utton switches automatically
ack to "Off” when you release it.
Only one station can talk at a time. A linking power LED indicates that talking is active.
Example:
The “Mic” utton of the mo ile device is set to permanently on. If the console “PTT” utton is pushed, the mo ile
device is not allowed to talk anymore, until either the console deactivates talking or the mo ile device switches
the “Mic” utton “Off” and “On” again.
8.2 Volume Control
The mic/line in input gains are controlled y software and can e adjusted y turning the “Volume In” kno . After
20s of inactivity, the values are permanently stored. By pushing and holding (> 2s) the “Volume In” utton, the
gains can e reset to default which is indicated y a one time linking of the “Info” LED.
The speaker output volume is controlled y hardware and can e adjusted y turning the “Volume Out” kno .
§Speaker Damage when volume is too high
A too high speaker volume can lead to extreme loudness or an overload of the speaker. When
taking the devices into operation, turn off the speaker volume in order to avoid any damages.

Operating Instructions
8.3 Line In (optional)
The devices can optionally e equipped with a “Line In/Mic” switch utton and a “Line In” connector. The switch is
used to select the audio input source which can either e the mic or a line in signal. The line in signal can e
connected via the “Line In” connector. The input gains for the mic and line in signal can e adjusted
independently.
8.4 Line Out (optional)
An optional “Line Out” or “Audio-Out” connector allows routing of the audio signal received via optical link to
other devices. This is especially used in 2 channel console devices which don’t have integrated speakers.
8.5 Secondary Mic (optional)
An additional option for the console device is a connector for a secondary microphone unit. This unit consists of a
microphone and a PTT utton with integrated LED. Either the secondary mic or the console device can talk with
the mo ile device at a time. A linking power/PTT LED indicates that talking is active.
Example:
The console device is set to permanent talking. If the PTT utton of the secondary mic is pushed, the mic of the
console device is deactivated and the secondary mic is activated. When talking is deactivated at the secondary
mic, the mic of the console device is NOT activated again. In order to talk again, the PTT of either the secondary
mic or the console device must e pushed.
8.6 Headset Connection (optional)
If the device has installed the headset option, an external headset can e connected to the device. The headset
can e activated/deactivated via the “Headset On/Off” switch utton. When the headset is activated, the speaker
is deactivated and full duplex operation is possi le without acoustic feed ack. E. g. oth devices can talk
simultaneously. When headset is deactivated, the integrated speaker is activated and only half duplex operation is
possi le. In this mode only one device can talk at a time.

Operating Instructions
9 Battery and Charger
9.1 Properties
Batteries are either integrated into the devices from mk messtechnik Gm H or delivered separately as external
attery packs.
The num er of cells varies and depends on the required voltages.
The related charger has the following properties:
•Power supply with power plug (Standard EU (type C or F) unless ordered otherwise, optional US (type A), UK
(type G), AU (type I))
•Integrated LEDs to display the charging level of the connected devices respectively the connected attery
packs.
•Short-circuit-proof, reverse polarity protected
•Suita le for atteries with 4 … 10 cells and a capacity of 1,0 … 10,0 Ah
•Charging process IUoU
Chargers with the charging process IUoU work asically identical to those using the IU (CCCV) charging process.
After reaching the end of charging voltage however, the device switches to trickle charging. This way a self-
discharge is avoided.
9.2 Regulations and References
Protect the atteries from heat (e.g. long exposure to direct sunlight) and fire. Do not immerse the atteries into
fluids. Otherwise there is a risk of explosions.
§Risk of Damage and Explosion Because of Incorrect Treatment
Unintentional or incorrect treatment can damage the atteries, which can even lead to
explosion of the atteries!
Batteries that are integrated into the devices of mk messtechnik Gm H or are delivered with them, may only e
charged with the intended chargers from mk messtechnik Gm H.
These components are compati le to each other, other chargers may damage the system or may reduce the
capacity or life span of the atteries significantly.
Respect the following references when operating the chargers:
•Use chargers only for charging devices and batteries.
•Switch devices off efore connecting the charger.
•Do NOT switch on the device during the charging process.
•Maximum charging current 1.2 A.
•Disconnect charger efore turning on the device.
•Prior to first use, charge the atteries completely.

revision 1.0 Intercom
Operating Instructions
•Charge the atteries efore use if you have not used them for a longer period (self discharge of the NiMH
atteries) and after use.
•To avoid capacity loss due to the memory effect, discharge the atteries completely every 5 charging cycles. To
do this, leave the device on, until it turns off y itself. Then start the charging process as descri ed a ove.
§Risk Through High Voltage at the Charging Device
•The charger works with mains voltage.
•Security references for work with mains voltage must e followed.
!
Warning of Reduced Capacity and Life Span of the Batteries due to Maloperation
Use only the intended chargers from mk messtechnik Gm H.
Powered devices must never e used with a connected charger, e.g. for uffering an empty
attery.
Disregard can lead to a loss of capacity and a shortened life span of the attery in a short time.
9.3 Charging the Batteries (Battery Pack or Integrated into the Device)
Start of the Charging Process
•Place the attery pack or the device to charge onto a sta le and skidproof surface.
•Turn off the device (see appropriate chapter for operation and operating controls).
•Connect the charger with the attery pack or the device using the designated screw connector (see
