CLOCKIT RADIO SLATE

SUPPLEMENT

The clockit radio slate is a combination of a small UHF telemetry receiver
powered by a 9Volt battery and a receiver built into the Masterslate. This makes
the unit more compact than external receivers and easier to use. The range can be
upt to 200 meters but in difficult conditions it is typically 50 meters.

TRANSMITTER

The transmitter is built into a milled aluminium case which is very strong. A
sliding lid exposes the battery compartment. The battery can be removed by
levering out or shaking. The on/off switch and the antenna socket is on the other
end.

The longer the led lights on switch on the lower the battery voltage.

The led stays permanently on when the battery has reached 5 volts. The
battery should then be changed but the unit may still work

RECEIVER

The receiver is built into the slate and can be turned on and off with the yellow
switch under the slider to the right of the dip switches. The switch removes the
supply, and the timecode line from the TC input  when switched off. The reason
for this is to remove receiver noise from the input when the receiver is not
receiving timecode.

Note. with the receiver on and the transmitter off their will be noise in the
timecode input line making the led glow red. In the generator mode the
radio receiver must be switched off to jam the generator through the
Lemo socket as the noise otherwise corrupts the incoming timecode
signal. Of course the generator can be set from timecode received by the
receiver but not the socket and the receiver at the same time.

If the timecode transmitter is on but no timecode is being transmitted then the
noise output of the receiver will be much less. Always switch off the receiver
when not in use.
When receiving timecode from the radio link the slate generator also can be
jammed from this timecode or the slate can run in both reader modes.

Note some Steadycam and camera focus remotes use the same frequency
as our timecode module leading to poor reception and low range,
 (interference).  If problems arise frequently the frequency can be changed

LARGE WRITING SLEEVE.

Due to users requests we offer a larger writing sleeve for the ACD master slate.
The width is a standard 11 inches „ Fits in a front box „ and the surface is
covered with a non reflective laser engraved label. Standard boxes are etched in
the surface.
