PHOS

INTRODUCTION

Phos is a powerful and compact diving torch, with a

20 W Xenon bulb that provides a full 500 lumen of

light output.

The careful choice of materials makes this a rugged,

hard-wearing lamp that can withstand depths up to

100 meters. The computer-designed reflector

provides a tight beam, ideal for night dives or low

visibility conditions.

The electronic control of the voltage supply to the

bulb maintains a consistently white light for the entire

rated burn-time, as well as prolonging bulb life. The

power selector allows the diver to choose between

two different brightness levels, according to need.

The nickel metal hydride battery, with no memory

effect, can be recharged even when it is not fully

discharged. A simple safety catch prevents

accidental switch-on of the torch. An anatomical

handle and perfect balancing make the Phos

extremely easy to handle underwater.

USER INSTRUCTIONS

SWITCH-ON AND SWITCH-OFF

Phos is equipped with a mechanical button that

operates an internal microswitch and electronic

control logic. When the dive lamp is off, pressing the

button activates an electronic circuit which turns on

the lamp at maximum power; pressing the button a

second time switches the lamp to the lower power

level. Pressing the button another time puts the

constant-brightness regulator in the stand-by

condition, switching off the dive lamp.

If during operation the internal temperature

becomes too high, a temperature control circuit is

triggered that switches off the lamp.

Another electronic circuit protects the battery pack

against excessive discharging. By monitoring the

voltage level, the lamp is switched off when the

battery power falls below the minimum threshold.

To guard against accidental switch-on, Phos is

equipped with a simple and effective mechanical

safety catch which prevents the button from

operating the internal microswitch (Fig. 1).

WARNING

The burn-time specified in the technical

characteristics is influenced by a number of

factors:

- operating temperature;

- temperature at which the lamp has been

stored when not in use;

- charging and discharging cycles of the

battery.

WARNING

Before using the diving light, carefully

read the instructions below.

FIG. 1

RECHARGING

The battery does not need to be removed for

recharging: simply unscrew the front part from the

outer lamp body. This prevents any gases produced

by the batteries during charging from being trapped

inside the lamp.

Removing the front part of the lamp uncovers the

charging socket and the reflector-holder, which has

a two-fold function:

 together with the special lamp-holder socket, it

disperses the heat of the bulb;

 during the recharging cycle, it protects the bulb

from knocks and accidental contact.

To start the charging cycle, insert the battery

charger pin into the lamp socket and plug the

charger into the electrical wall outlet (Fig. 2).

FIG. 2

The Phos has two indicator lights which signal:

 presence of mains voltage when the battery

charger is connected (green LED illuminated);

 charging cycle complete. The yellow LED

illuminates during charging, and switches off

when charging is complete.

Complete charging takes approximately 5 hours.

The battery pack should not be left under charge once the

indicator illuminates to signal that charging is complete.

When the charging cycle is complete, unplug the

battery charger from the wall outlet, then

disconnect the charger pin from the lamp socket and

reassemble the outer lamp body.

The use of NiMH batteries considerably reduces

problems with the "memory effect", as compared

with Nickel Cadmium batteries. Nevertheless, after

approximately 15 partial charging cycles, it is

recommended to completely discharge the battery

pack before charging. The fully discharged condition

is signaled by the triggering of the circuit that

protects against excessive depletion of the battery

charge, which switches off the lamp.

WARNING

When recharging a fully discharged

battery, it may take a few minutes before

fast charging mode begins (yellow LED

illuminates).

WARNING

During battery charging it is not possible

to switch on the lamp.

WARNING

Use the battery charger provided. Use of a

different charger may damage the battery

pack and the electronic circuits.

WARNING

Perform a full battery recharging cycle before

using the diving lamp for the first time.

WARNING

After use, be sure to engage the safety catch

to guard against accidental switch-on.

WARNING

Do not switch on the lamp outside the

water, especially if using a 35Watt bulb.

ROUTINE MAINTENANCE

Rinse the diving lamp in fresh water before putting

it away.

Check that the O-Ring seats and the threads are free

of impurities (sand, salt etc.).

Apply a film of silicone grease on the seals.

REPLACING THE BULB

Open the front part of the lamp body, then remove

the reflector holder. This exposes the lamp holder

which is fixed to the battery by a set of springs.

Replace the bulb and the reflector holder. If

necessary, adjust the focus by moving the lamp-

holder closer to or further from the battery by

adjusting the spring fixing system (Fig. 3).

FIG. 3

REPLACING THE BATTERY

To replace the battery it is necessary to unscrew the

body from the base and pull out the tube. This

exposes the battery and the reflector holder. The

battery is connected to the electronic control circuit,

incorporated into the base, through three

connectors. Simply pull it out from the bottom to

remove (Fig. 4).

FIG. 4

Remove the reflector holder and the bulb, which

must be affixed to the new battery.

To reassemble, replace the temperature control

circuit inside the new battery pack, then fit the

centering pin and plug in the connectors.

The pin also serves to prevent incorrect insertion.

RECHARGEABLE BATTERY

WARRANTY

The rechargeable batteries are guaranteed against

defects in materials and workmanship for a period of

6 months from the date of purchase

6 months from the date of purchase.

WARNING

Remove the battery pack with great care.

The battery pack contains the temperature

control circuit, connected by means of a

cable to the main circuit fixed to the base.

Therefore, if the battery pack is removed

forcefully, the connection between the

two electronic circuits may be damaged.

WARNING

Do not touch the halogen bulb with the

fingers, but use a clean cloth.

WARNING

Apply a few drops of lubricating oil

externally, to the seat of the mechanical

button.
