• Storage: Store within specified temperature limits. Check accuracy after prolonged storage.
• Transport: Always use the original packaging or an equivalent container. Switch off the device before transport.

Troubleshooting

• Device on, no display: Battery flat, inserted incorrectly, or device/switch faulty. Replace or reinsert batteries.
• No laser beam: Battery flat. Replace batteries.
• Display frozen: Program error. Remove batteries, wait one minute, and reinsert.
• Laser lines blink: Battery flat. Replace batteries.
• Display lit but no laser: Ambient temperature too high/low or laser control faulty. Allow to acclimatize or contact dealer.
