Warranty:
MGL avionics warrants their products for a period of one year from date of purchase against
faulty workmanship. Warranty is limited to the replacement of faulty components and includes the
cost of labor. Shipping costs are for the account of the purchaser.
Note for operation on supplies with inductive loads:
Any operation of electronic instrumentation on power supplies that are subject to high voltages
caused by operation of inductive loads (starter motors, solenoids, relays) are required to be fitted
with suitable protection.
All Smart Singles are guaranteed to withstand temporary over voltage up to 40V without
additional protection. We recommend that measures are taken to prevent voltage transients in
excess of this limit.
MGL Avionics recommends the fitment of a fuse in line with a 33V transorb (available from MGL
Avionics at low cost) to protect electronic instruments, radios and intercom systems. Only one
such arrangement is required for a cluster of instruments.
Please note that product warranty excludes damages caused by unprotected, unsuitable or
incorrectly wired electrical supplies.
