Petzl Duobelt LED 5 E73 P User Manual



E73P E76P   DUOBELT LED 5   DUOBELT LED 14    E73503 Révision D (2101006)

Waterproof with dual light source: focusable halogen bulb and an LED 

module. 

These lamps are ideal for use in wet environments, but are not 

designed for prolonged submersion (i.e. diving).

Move the switch up to select the powerful halogen beam - high energy 

consumption (). 

Move the switch down to select the LEDs - low energy 

consumption (3). 

The zoom button allows focusing the high beam as needed. Turn it 

down for a narrow spotlight, or up for a wider beam (). 

The DUOBELT lamps allow the light to be optimized (distance, 

duration) according to your needs. 

Simultaneous use of both bulbs is not possible.

The 5 LED light source offers one very economical lighting level. The 

light gradually diminishes in brightness as the batteries are depleted.

The  LED light sources are electronically regulated. The electronic 

current-regulating system maintains constant brightness. It has a 

reserve power mode that activates automatically when the batteries are 

nearly spent, giving low-level proximity lighting and greatly extending 

burn time. 

In addition, the  LED light sources provide 3 power levels. 

. OPTIMUM: ideal balance between power and burn time. 

. MAXIMUM: maximum power. 

3. ECONOMY: maximum burn time. 

You may select the power level most suitable to your activity. 

Move the switch down (on). The system is intially set to OPTIMUM. 

To select the next lighting level (MAXIMUM), turn the switch off, then 

immediately back on. 

Consecutive off-on movements of the switch will cycle the light 

through levels  and 3, then back to level  again. 

If the movement of the switch is not quick enough, the lamp will light 

up at level . 

When the batteries are nearly spent, the light automatically switches 

to Reserve Power Mode, providing low-level lighting for an extended 

period of time.

Remember to lock the switch during transportation and storage by 

pressing the red button (A). To unlock, press on the other end of the 

red button (B). If the light accidentally turns on in your pack, the heat 

produced by the halogen bulb can damage the lamp.

To open the battery case, unlock the two clips (5). 

ATTENTION, prolonged storage: remove the batteries. 

To avoid a buildup of pressure from gaseous emissions inside the 

case, each DUOBELT is equipped with a gas absorber pellet (see 

illustration). With each change of batteries, check the pellet. If the 

pellet is defective (crumbling, broken, missing), contact Petzl’s After-

Sales service. If the pellet gets wet, let it dry naturally in open air.

Use alkaline batteries or NiMH rechargeables. 

- The batteries must be inserted correctly w/respect to polarity by 

following the diagram on the battery case. 

If one battery is reversed (two + poles or two - poles in contact with 

each other), a chemical reaction is produced in minutes that releases 

explosive gasses and extremely corrosive liquid. 

Indicator: a weak level of light with new batteries indicates that the 

polarity of one or more batteries is reversed. 

In case of doubt, turn off the lamp immediately and check the polarity. 

Protect your eyes in case leakage has already occurred. Cover the 

battery case with a rag before opening it to avoid contact with any 

discharge. 

In case of contact with liquid from the batteries, rinse affected area 

immediately with clear water and get immediate medical attention. 

- Do not mix brands of batteries. 

- Do not mix new and used batteries.SFlb- Remove the batteries from 

the lamp for prolonged storage. 

- Do not recharge alkaline batteries.SFlb- Do not short-circuit the 

batteries as this can cause burns.SFlb- Do not attempt to open or 

dismantle batteries. 

- Do not put used batteries in a fire. 

- Keep batteries out of reach of children.

- no not allow the batteries to become heavily discharged, 

- keep water out of the battery case.

Lamps, bulbs, and batteries should be recycled. Do not throw them 

in the regular trash. Dispose of these items by recycling them in 

accordance with applicable local regulations. By doing so you play a 

part in protecting the environment and public health.

Open the headpiece using the left hand to unscrew the bezel (6). 

Remove it completely. If it jams, try a penetrating fluid, or warm the 

front cover with a hair drier. 

Halogen bulb: unscrew the burned out bulb and screw in the new one, 

tightening it securely. 

LED module: pull the unit straight out (it’s OK to touch the LEDs). 

Install the new unit, being careful not to bend the contacts or LEDs. 

Check the alignment of the LEDs. 

To close the head piece: 

- position the reflector, lens, and bezel correctly over the head 

piece (7), 

- using your right hand, screw the bezel onto the head piece until 

the mark on the bezel is situated between the two marks on the head 

piece (8 & 9).

Make sure the batteries are good, and that they are properly installed 

with respect to their polarity. If the polarity is simply reversed in the 

battery case, the halogen bulb will work but the LEDs will not. Follow 

the order and position as indicated on the battery case. 

Try the spare bulb. Check the contacts for corrosion. If corroded, 

gently scrape the contacts clean without bending them. 

Work the switch several times. 

The LEDs often give better light than the halogen bulb when the 

batteries are cold or low. 

If your lamp still does not work, contact PETZL.

Water in the headpiece or battery case can cause the lamp to 

malfunction. Whenever the lamp has been used or opened in poor 

conditions (moisture, mud, dust…), remove the batteries, bezel and 

bulb. Allow the lamp to dry thoroughly, keeping the battery case, bezel, 

and headpiece open. Clean the seals with water and lubricate them 

with silicone grease.

Wash the lamp, with the compartments closed, in clean water. Use 

soap for the elastics. Do not rub with an abrasive product especially on 

the lens. Do not wash with a high pressure hose.

Conform to the requirements of the 89/336/CEE directive on 

electromagnetic compatibility.

The DUO LED  may interfere with the functioning of an avalanche 

beacon. This can happen only when the  LED modules are turned 

on, and the lamp is near a beacon in receive (search) mode. 

In case of interference (indicated by static noise from the beacon), 

move the beacon away from the lamp until the noise stops, or switch 

off the LED module and switch on the halogen bulb.
