Wrist Lanyard

The AP3 lanyard can be a convenient aid to pull the AP3 out of your pocket, or to put over your wrist, freeing your hands to hold other objects.

Your AP3 should let you attach the lanyard at the top or bottom, although some early units allow you only to attach it at the bottom.

The easiest way to attach the lanyard is to:

  1. Unclip the lanyard by squeezing the clip at its base.
  2. Remove the back-plate of the AP3 by running a finger nail around the back-plate - it's easiest to do this starting at the power button.
  3. Thread the lanyard cable through either the top or bottom holes on the AP3 back-plate by inserting from the outside of the back-plate first, then back out through the corresponding hole.
  4. Pass the lanyard clip through the hole in the cable and then re-connect it to the rest of the lanyard.
  5. Your lanyard should now be attached to the back-plate and you can now re-attach the back-plate by simply pressing it onto the back of your AP3. Make sure the battery is still in place while you do this.
  6. Success!

To detach the lanyard, you can simply follow the above instructions in reverse.


Before its first use, please fully charge the AP3. Connect the provided USB cable into a computer's USB port, or plug the cable into a 5V USB Power Adapter connected to an AC (Mains) power outlet and turn on. Now, connect the micro USB end of the cable into the AP3. The AP3 will turn on when charging, this is normal. A full battery charge will take approximately 3 hours.

AP3 Charging


Output from Power Adapter must not exceed 5V.

Power adapter compatibility

5V USB Power Adapters are readily available for purchase from most electronics retailers, alternatively, you can purchase a 'Quest Certified' 5V USB Power Adapter directly from Quest. Contact Quest for more information.


The AP3 is fitted with a 340mAh Lithium Ion Battery. To maximise the Battery life span, avoid full discharges and charge the battery more often.

Partial discharge on Li-ion is fine; there is no memory effect and the battery does not need periodic full discharge cycles to prolong life.


Do not store the device for extended periods with a depleted battery. Doing so may result in permanent damage to the battery or the device.

Turning Off

Hold the power button for 3 seconds until your hear a beep tone, then release the button. When turned off, the AP3 will display OFF on the screen.


You will need to wait 5 seconds after turning off before attempting to turn the AP3 back ON.


Because the AP3 uses an eInk display, if something goes wrong then it is possible for the display to appear to be on even when the AP3 is off. If the AP3 is not responding then follow these steps:

  1. Hold down the power button for 10 seconds to force it to turn off (don't worry if the screen still appears to be on)
  2. Next, hold the power button for 3 seconds to turn the AP3 back on
  3. If this doesn't work then the AP3 might be out of power, in this case plug in your micro USB cable and charge it


Regular cleaning is recommended and care should be taken to avoid excessive dust / dirt/ fluff / moisture.


Turn off the AP3 before cleaning. Use a clean, micro fibre cloth to gently wipe the display when required.


Avoid getting moisture in openings. Do not use window cleaners, household cleaners, aerosol sprays, solvents, ammonia, or abrasives.
