ARROW 50T DESCRIPTION OF THE UNIT
The system AEQ ARROW 50T base transmitter is a long range radio link with
broadcast quality audio, designed for easy handling and high reliability.
This device is implemented using the latest electronic and manufacturing
technologies (SMT) and high quality components.
This transmitter is a multichannel system in VHF range with very complete
protection system.
The transmitter has a select mic/line audio input and gain adjust. This audio signal
of very high quality is submitted a compression/limitation system with preemphasis of 50/75 us (upon request).

ARROW 50T STARTING
Please check that you are using the appropriate antenna and it is correctly connect,
because the equipment have a high RF power.
After this, you must do the following:
If you use 115/220 VAC, connect the cable, checking that the ON/OFF
switch is in OFF.
Connect the equipment, switch ON.
Check the channel selected.
Connect the audio input with the correct level gain.
All ERROR indicators should be switch off.

ARROW 50T POSSIBLE PROBLEMS AND SOLUTIONS
1. SWITCH ON the 12V indicator is not lighting:
Check that the cable is correctly connected.
Check that the DC bridge is correctly placed.
Check fuse status.
2. SWR indicator is lighting:
Check the antenna position and connection are correct.
Press the RESET button, if the error persists, switch OFF the equipment
and check all the connections and procedures of starting.
3. Thermal indicator is lighting:
Check the external equipment temperature.
Press RESET. If the problem is the same, switch off and cool the
equipment. After this procedure, switch ON the equipment.
4. In the normal working, the SWR indicator is lighting:
Check the antenna connection, position and status.
Press the RESET button and if the problem persists, switch OFF the
equipment.
5. In the normal working, the thermal alarm is lighting:
ƒ
ƒ
Check the external equipment temperature.
Press RESET button. If the problem continue, cool the equipment totally
switch OFF
6. Transmitted audio is distorted:
Check the audio input level gain.
Check audio Rx output
Normally we recommend installing the equipment in a good ventilated place. Also is
very important in order to get the best characteristics of the equipment the correct
position of the antennas in order to obtain the best radio link.
Please check the RF spectrum and the frequencies range that you will use in order
to select the most favourable channel in each moment.

ARROW 50R POSSIBLE PROBLEMS AND SOLUTIONS
1. If the receiver is connected and there is not audio:
- Check the power connection
- Check that Tx and Rx are in the same channel.
- Check the volume
- Check the antennas.
2. If you use several systems and you obtain interferences:
- Check the channels to prevent intermodulations
- Check that you don’t have two equipments working in the same frequency
3. The audio quality is not the best:
- Check the RSSI
- Check the Rx audio signal is not distorted
- Check the antennas
