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. 
 
This instrument is not certified by the FAA. Fitting of this instrument to certified aircraft is subject 
to the rules and conditions pertaining to such in your country. Please check with your local 
aviation authorities if in doubt. 
This instrument is intended for ultralight, microlight, homebuilt and experimental aircraft. 
 
Operation of this instrument is the sole responsibility of the pilot in command (PIC) of the aircraft. 
This person must be proficient and carry a valid and relevant pilots license. This person has to 
make him/herself familiar with the operation of this instrument and the effect of any possible 
failure or malfunction. Under no circumstances does the manufacturer condone usage of this 
instrument for IFR flights. 

 

Important information: 

 
Depending on laws and regulations in your country you may not be allowed to install a 
transponder and associated equipment yourself. This work may have to be done by a certified 
AMO or instrument technician. 
Please check with your relevant authorities.
