HUMANTECHNIK RM241800 Acoustic RF Receiver
Operation Instructions
Acoustic RF receiver
Congratulations on purchasing your acoustic RF receiver. We hope it will provide you with many years of service. You have chosen a modern and reliable system. Please read through these operating inst-ruction carefully to be able to start the unit correctly and to familiarise yourself with all of the system’s features.
Standard components
Please check if all the following components are included:
- Acoustic RF receiver
- 9 V plug-in PSU
- Operating Instructions
- Warranty card
If any parts are missing please immediately contact your dealer or the manufacturer directly.
Function
The acoustic RF receiver picks up signals from different lisa RF radio
transmitters and converts them into audible alerts.
In addition, 6 event indicator LEDs help you to identify the various alerts.
Controls
Battery/Dead battery
If the battery status indicator lights up constantly, this means that the
battery or rechargeable battery used is almost depleted. A regular battery
must be replaced or a rechargeable battery recharged. The battery status
indicator might flash briefly in the flashing mode; this does not indicate
that the battery is low.
Event indicator LEDs
The 6 indicator lamps help you to differentiate between the individual
transmitter signals. They light up for a total of 40 seconds.
Lisa-Channel selector
You can select the radio channel using the channel selector.
ON-/OFF switch
Set the on/off switch to »ON«. The acoustic RF receiver is now ready to
operate. After the unit has been switched on, each of the indi-cator lamps
lights up briefly in succession. This forms part of a self-test of the unit
and lets you know that it is functioning correctly.
OK button
Press the OK button to acknowledge incoming signals. This will switch off the
acou-stic signal. The indicator lamps light and go out automatically after a
total of 40 seconds. Furthermore, you can press the OK button to call up the
most recent signal again (the function works for up to 3 minutes after receipt
of the signal).
The acoustic signal will not be repeated.
The setting of the volume
- Volume: continuously adjustable (max. 100 dB)
Note (special accessory)
Vibrating pillow or other modules:
- Flash module MF-1
- Switch module MS-1
can be connected to the corresponding jacks of the acoustic RF receiver.
The following audio devices can be connected to the 3.5 mm audio out jack:
- Infrared transmission systems
- Radio transmission systems
- Induction loop transmission systems
- Hi-fi systems or active speaker systems
Setting up the system
Mains operation
Insert the plug at the end of the 9 V power supply into the corresponding jack
on the rear side of the acoustic RF receiver. Then plug the power supply unit
into the normal 230 V socket in your house.
Power failure backup
Please note that the device is designed for mains operation. The battery and
recharge-able battery are used as backup only in the event of a power failure.
Inserting the battery
The acoustic RF receiver can also be powered by a 9 V block battery (not
included with the device). There is a battery compartment located on the rear
side of the acoustic RF receiver. Open it by sliding the cover of the battery
compartment to the right of the receiver using your thumb. Connect a 9 V block
battery to the connector plug, place the battery into the recess and close the
receiver again. When the battery is connected, the receiving signals may be
triggered once.
1c. Inserting the rechargeable battery The acoustic RF receiver can also be powered by a rechargeable battery (A-2995-0), which is available as a special accessory. Open it by sliding the cover of the battery compartment to the right of the receiver using your thumb. To connect the rechargeable battery, insert the battery plug into the outlet in the battery compartment. The separate re-chargeable battery connection makes sure that a 9 V block battery will not be recharged by mistake. The rechargeable battery is recharged when the acoustic RF receiver is connected to the mains power supply.
Prior to using the rechargeable battery for the first time, it must be recharged for 12 hours.
For rechargeable battery operation, use and recharge only the special rechargeable battery A-2995-0. Rechargeable batteries cannot be recharged using the 9 V block battery connection!
Setting the correct radio channel
A special digital transmission process ensures that the radio signals are
picked up without errors. This process also makes it possible to set 10
different radio channels. When supplied from the factory, all-acoustic RF
receivers are set to channel 0. It is only necessary to set units to other
channels if you have several different users operating units in the same
building. Set the required channel by using a small screwdriver to turn the
channel selector switch, which is located on the right side of the unit, to
the required channel number.
All transmitters and receivers must be set to the same channel.
Example: Set channel number
Transmission signal detection
The acoustic RF receiver converts the signals sent by the lisa RF transmitter
into different sounds (telephone ringing, doorbell, baby cries, etc.).
At the same time, it is also possible to see which Lisa signal has been sent
because the corresponding LED will either flash or light up for 40 seconds.
- Telephone: The telephone LED lights up in orange and you can hear the sound of a telephone ringing.
- A door I: Door LED lights up in green and you can hear the sound of a doorbell.
- Door II: Door LED flashes in green and you can hear the sound of a different doorbell to the first one.
- Babycall: Babymonitor LED lights up in white and you can hear the sound of a baby crying.
- Person call: Person call LED lights up in yel-low and you can hear the pager signal.
- Alarm: All 6 LEDs flash and you can hear an alarm signal.
- Water alarm: Water-alarm LED lights up in blue and you can hear an alarm signal.
- Fire alarm: Fire-alarm LED lights up in red and you can hear an alarm signal.
Transmission range
Note the following points when using the acoustic RF receiver:
The radio signals are designed to have a range of 80 meters under optimum
conditions. The following conditions may result in a reduced range:
- Signal transmission through building structures or vegetation.
- Interference from TVs, computer monitors, and mobile phones. Under certain circum- stances, this may prevent the receiver from functioning at all.
- Positioning of the transmitter at an un- favorable distance from surfaces that reflect radio waves, for example, floors and walls. This may lead to the signal wave be- ing weakened or even canceled out by the reflected wave.
- Metallic objects reduce the range due to the shielding effect of the metal.
- Particularly in towns and cities, there may be many other sources of radio waves that can disrupt the original signal.
- Having units operating at similar frequencies located close to one another may also result in mutual interference.
Maintenance and care
The acoustic RF receiver does not require any maintenance. If the unit does become dirty, simply wipe it clean with a soft, damp cloth.
Note: remove the acoustic RF receiver from main socket!
Never use spirits, thinners or other organic solvents. Do not set up the
acoustic RF receiver where it will be exposed to full sun-light for long
periods. In addition, it must be protected against excessive heat, moisture
and severe mechanical shocks.
Note: This product is not protected against splash water. Do not place
any containers filled with water, such as flower vases, or anything with an
open flame, such as a lit candle, on or near the product.
Please make sure that the batteries are not exposed to excessive heat from
such as sunlight, fire or anything similar.
Warranty
The acoustic RF receiver is a very reliable product. Should a malfunction
occur despite the unit having been set up and operated correctly, please
contact your dealer or the manufacturer directly.
This warranty covers the repair of the product and returning it to you free of
charge. It is recommended that you send in the product in its original
