Technical Data:

Operating voltage……. DC 24V

Operating current……. < 450mA
Fuse…………………… 250V, 500mA
Sweeping frequencies….…. 7.6~8.2MHz
Modulation frequency..180Hz, 172Hz, 160Hz or 150Hz (factory setting at 180Hz)

Adjusting Modulation Frequency

The modulation frequency is preset at the factory at 180Hz.
Adjusting the setting at JP5, JP6, JP7 and JP8 will change the modulation frequency.

Disconnected Connected
180Hz JP5, JP6, JP8 JP7
172Hz JP5, JP7, JP8 JP6
160Hz JP6, JP7, JP8 JP5
150Hz JP5, JP6, JP7 JP8

For systems to operate, the Modulation Frequency of the Tx and Rx must be the same.

Multiple connections
Non-synchronization

If there are two or more groups of antennae which are 10m away from each other, and
synchronization is not suitable, it is necessary to change the modulation frequency of one
group from another to avoid interference between systems, i.e. one set of transmitters at
180Hz and while another set at 160Hz（or 150Hz or 172Hz）. For example, in figure 1 and

4 if the two sets of systems are over 10m apart, setting two different modulation frequency
for the two groups would be sufficient. However, for the set up in figure 2 and 3 ,
synchronization would be necessary (see section on Synchronization below).
