• Green light — Is on when the device is on powered by the batteries, and the batteries have enough power.
• Red light — Is on when there is not enough power in the batteries. Switches on for a short while also when the lock programming cable is inserted to the lock.
• Orange light — Is on when the device is communicating with the lock.

• Green light — The programming was done successfully.
• Green blinking light — The lock's log was read successfully.
• Red light — A programming error. The Programmer may contain, for example, an incorrect programming package type for the lock.
• Red blinking light — The Programmer memory is full.

• Red light blinks twice — The clock bus of the lock is short-circuited. Proceed as follows:

  • On Europrofile cylinders, retry programming. Do not turn the programming cable in the cylinder.
  • On oval cylinders, check the real-time clock wire for any damage.
• While programming the lock and after an orange BATT light, if the STATUS light is not switched on at all, and the BATT light returns to green, the Programmer memory contains no programming package intended for the lock.
• Orange light — The lock is already in the status to which you are attempting to program it.

A green light is on when the device is connected to a computer through a USB port. The device is powered through the USB cable.

If a Bluetooth module is connected to the device, a green light blinks momentarily after the power is switched on (the Programmer model P10S.20).

Green light is on when the device is connected to a computer using Bluetooth.

• Blinking red — The Programmer does not have a time. The Programmer cannot be used to program locks or to pick audit trails until its time has been synchronized with the locking system time, by connecting the device to iLOQ Manager.
• Blinking orange — The Programmer is updating a lock firmware version.
