Important
Do not mount an Indala PX 620 reader in an elevator car. The environment is unsuitable and causes the
reader to malfunction.
The PX 620 is factory tuned. If a PX 620 requires tuning, tune only once. Excessive tuning may
permanently damage the reader. Refer to the Indala documentation for instructions on tuning.
