Clearly marked controls

Status light
Sumo DM is the only digital Super Power instrument to include a Status light. This software-activated option indicates that:

The instrument is ON
The preferred VC level is reached
Power up
Program change

Three OFF options

1. VC: tactile OFF-click in VC wheel when turned to its lowest position
2. Program switch: OFF position can be programmed in software (optional)
3. Battery door: Instrument is OFF in open position

Smart VC with markings
The digital VC features distinct "start and end" positions plus visible markings. Intelligent eight-channel technology allows full-range gain adjustments without the risk of feedback.

Setting the VC at the preferred level is easy with the visible status light flashes and the preferred level beeps that indicate when the pre-programmed desired level is reached.
 

Program switch
The fully programmable switch has visible markings to suit the needs of both child and family, with up to three listening programs.

M: Listening program
MT: Microphone + Telecoil program*
T: Telecoil program*
OFF: Optional OFF program
