9. Service
If the unit requires service:
1. Use the troubleshooting section (section 8) to eliminate obvious causes.
2. Verify that no circuit breakers are tripped. A tripped circuit breaker is the most common unit
problem! See section 6.2.
3. Go to section 5.3 and perform a self-test to check the battery.
4. See the front of this manual for the correct telephone number. Call customer service for a return
material authorization number (RMA#). If customer service is not available in your area, call
the dealer that sold the unit.
■Note the model number of the unit, the serial number, and the date purchased. A techni-
cian will ask you to describe the problem and help solve it over the phone, if possible, or
will give you an RMA#.
■If the unit is under warranty, repairs are free. If not, there will be a charge for repair.
5. Pack the unit in its original packaging. If the original packing is not available, ask customer ser-
vice about obtaining a new set.
■It is important to pack the unit properly to avoid damage in transit. Never use styrofoam
beads for packaging. Damage sustained in transit is not covered under warranty.
■Include a letter with your name, RMA#, address, copy of the sales receipt, description of the
trouble, your daytime phone number, and a check (if necessary).
6. Mark the RMA# on the outside of the package. The factory cannot accept any package without
this marking.
7. Return the unit by insured, prepaid carrier to the address at the front of this manual.
