As the name suggests, the Simple (r01) is a no frills version of our popular v42 (Omni) module, for the Petzl Duo. Well suited to those who like the operation of their caving lamp to be really straight forward, yet practical. Now providing light output up to 430 lumen, seperate low power side LED and battery charge indication.

Simple (r01)

Operating the switch very quickly, on-off-on ('double switch') will turn on low power side LED. At this point, the main LED will blink 1 to 5 times to indicate the approximate level of battery charge.  

 
The Simple features a 3 second 'first' mode memory. When lamp has been on for more than 3 seconds in any setting and is switched off, then it will automatically restart at the first setting (low) when next switched on. 

 

The Simple constantly monitors temperature. If the module is too hot, it will automatically step the power down to a lower level of light in order to protect the LED, and remain at this level until next switch operation.

 

The Simple (r01) has zero battery consumption when switched off, so there is no requirement to disconnect batteries. However it is probably best practice to do so when not in use for more than a few days, to reduce any stress on battery contacts in Duo box.

The Simple (r01) has three power settings (see following table). To switch between the settings, use the down switch on the Petzl Duo. Switch on-off-on-off etc, to move between settings 1-2-3 ... 1-2 etc, in a looping sequence. Setting 1 (low) will blink momentarily when selected to make it very easy to determine where you are in the sequence, and which setting has been selected.
