Maintenance
Although this photocell is built to work in hard conditions, we
advise you to open sometimes the aluminium cover and to let it
dry when the photocell has been exposed to humidity.
Special Note
In case you use an external power supply, we advise you to
place, in any case, 3 internal batteries. These will insure the
functionning of the photocell in case of current cut off or falling
voltage.

HL 2-35 PHOTOCELL
USER’S MANUAL
DESCRIPTION
The infra-red photocell HL 2-35 is composed of one transmitter (HL 2-35E) and one receiver (HL 2-
35R) with internal or external power supply and adjustment of duration of output impulse. This photocell
offers exceptional quality for the price, satisfying the most exacting requirements of sports timing.
Principle
Transmitter
Receiver
The above photocell works perfectly with a distance between transmitter and receiver of up to 40 m.
(130 ft.) in "LOW" position and up to 80 m (260 ft) in "HIGH" position.
OPERATION INSTRUCTIONS
Switch on the transmitter with
➁
in LOW or HIGH mode.
Switch on the receiver with
➁
.
a) Battery check
When you switch on the photocell, the LED
➂
"BATT" illuminates briefly and goes out.
I
New Batteries
➂
does not illuminate
II
Used batteries
➂
flashes slowly (once every 2 sec.).
The batteries insure at least 30 hours of functioning at 20° C.
III
Flat batteries
➂
flashes rapidly (once every sec.).
The batteries must be replaced. If this arises during the
timekeeping the batteries will insure at least 6 hours of
functioning at 20° C.
