SCUBAPRO PHAD LIGHT - USER MANUAL
Welcome to SCUBAPRO and thank you for purchasing the Phad Light. This
manual provides you easy access to SCUBAPRO Phad's key features and
functions. Should you wish to know more about SCUBAPRO UWATEC diving
equipment, please visit our website www.scubapro.com.
Phad Overview
Housing
The casing of the SCUBAPRO Phad 4 and Phad 8 battery pack is made of
ABS, a lightweight, low-friction and wear-resistant plastic. The casing of the
SCUBAPRO Phad 4 and Phad 8 light head is made of salt water resistant alu-
minum. These light heads have been treated with three processes to produce
a hard, corrosion-resistant surface.
Water Tightness
The Phad 4 and Phad 8 battery packs and light heads obtain their water tight-
ness by means of durable NBR O-rings. These O-rings are extremely important
and require your special care and attention. The O-rings must be free of impuri-
ties and grooves; they should shine slightly due to silicone grease. If not, the
Orings should be cleaned with a soft cloth that does not shed fl uff and then
lightly greased with silicone grease. Every time the SCUBAPRO Phad batteries
are replaced, the condition of the O-rings should be checked. It is advisable to
replace these O-rings when in doubt about their condition and in any case after
approximately 50 dives. They must be replaced with great care. The condition
of the seal's surface should also be checked for damage.
Rinsing
After each dive, it is highly recommended to rinse your SCUBAPRO Phad bat-
tery pack and light head with fresh water. While rinsing make sure that the
battery pack is attached with light head and umbilical (if applicable) to prevent
water entering the system.
!
WARNING!
The batteries used in the SCUBAPRO Phad 4 and Phad 8 battery packs
are non-rechargeable alkaline batteries. Recharging these batteries will
damage this unit and may cause personal injury. In case these batter-
ies are replaced with rechargeable batteries, the manufacturers guide-
lines concerning charging and recharging of these batteries are to be
followed.

Using your Phad light
Phad 4 and Phad 8
To switch on the light, the light head must be screwed down into the battery
pack or into the umbilical (if applicable). To switch off the light you can unscrew
the light head half a turn. SCUBAPRO Phad 4 and Phad 8 light heads are
equipped with an undertension security to prevent deep discharge as deep
discharge will cause irreparable damage to rechargeable batteries.
As soon as the voltage of the Phad 4 and Phad 8 battery packs gets too
low, the Phad 4 and Phad 8 light heads will be dimmed and set to the 'bring-
me-home' mode. The 'bring-me-home' mode will provide another 72 hours of
dimmed light, powerfull enough to read instruments and compass.
The Phad light heads are equipped with a PWM-module (Pulse Width
Modulation)
Pulse Width Modulation is controlled by a microprocessor which:
- enables a perfect battery management which also prevents damage
by deep discharge;
- controls the LED's at their maximum capacity without overload;
- protects the light head against overheating by constantly measuring
the temperature and by reducing the current when necessary;
- offers extra options such as dimming, SOS and strobe mode, ...
Using the dimmer in the Phad light head
At startup, your Phad light head will burn at 100%. When restarted within 5 sec-
onds, the dimmer will reduce the output to 50%. When restarted after a burn
time of more than 5 seconds, the light head will start up at 100%.
Using the strobe mode in the Phad light head
When restarted within 5 seconds after reducing the output to 50%, the light
head will be set to strobe mode. When restarted, the light head will start up
at 100%.
Important
While burning, a dive light produces light as well as a certain amount of heat.
Extensive use of the light out of the water will prevent it from cooling down and
may result in overheating. The Phad 4 and Phad 8 light heads however are
equipped with an overheat protection which will reduce the output when the
temperature of the light head gets too high.
