Service and Maintenance
The Loki receiver and Loki transmitter are designed to require minimal
recalibration. However, as with all safety equipment, it is recommended that they
are serviced and have their calibration validated using Schonstedt approved test
equipment. Schonstedt accepts no responsibility for service, calibration or repairs
carried out by non-authorised persons.
Functional test
Schonstedt recommends that you perform a daily functional test on the Loki
receiver and Loki transmitter before use. To perform the function test;
1. Place the transmitter on the ground.
2. Switch the Loki Transmitter on and check for an audible sound. If no sound is
heard, replace the batteries before use.
3. Switch on the Loki receiver by squeezing the trigger, checking for an initial
‘chirp.’ A low tone indicates low batteries. If no sound is heard, replace the
batteries before use.
4. Rotate the Loki receiver function switch and check that the appropriate icon is
displayed in each position of the switch (as per the ‘Modes’ section earlier on
in this guide).
5. Set the Loki receiver and Loki transmitter to the same active frequency.
6. With the Loki receiver in Transmitter mode (T), set the sensitivity at its
maximum gain, hold at waist height pointing toward the Loki transmitter with
the flattest part of the housing parallel to the ground and check that the Loki
receiver can detect the Loki transmitter up to 49’ (15m) away with a clearly
audible sound.
