II As of January 1st, 2018, LB Altimeters no longer service or repair VISO II unlessthe unit has been purchased from an LB official dealer within 2 years. This means, that the customer has to pay for the repair and the shipping of all LB units that are more than 2 years old unless the customer can show an official invoice from an authorized dealer. This is especially true of broken cases on all units.



LB Altimeters retains the exclusive right to either repair or replace the unit with a "newly-overhauled" (NOH) unit or new unit at its sole discretion. The same policy shall apply to software.

The following units are no longer under warranty:

  • Original VISO, OPTIMA and SOLO with the side button battery compartment
  • Original PROTRACK
  • Original DYTTER
  • ALTITRACK with firmware below 1.07. Firmware version is shown on the LCD on the back of the unit when powering up



VISO II+: Freeze on landing: The unit needs to be updated to the latest firmware.


  • Batteries MUST be Renata CR 2325, not clones from China. We have seen numerous 'failing' units that work properly with the right batteries and the right reset.
  • Installment of the right batteries and the right reset.
  • Master reset when reaching 999 jumps. The VISO II+ will not count above 999: Middle button pressed while doing a reset. Keep pressing the button until beeps are done.



  1. Send an email to one of our service centers explaining the problem and include pictures (if available). See below for email address
