# Maytag - MHN30PD with busy signal & coin acceptor


### Recommended dashboard setup

Fixed ➜ Pulse operated
pulse length: 50 ms., pulse repetition: 1, busy signal: Low

If the Airwallet unit is installed on a machine that also allows for coins, then the pulse repetition must be equal to the price divided by the std. coin value. 
E.g. The price of a dryer is 1 £ and the machine standard coin value is 0.25 £. Therefore the pulse repetition is 4 pulses.

### Recommended machine setup

Set the machine to vended laundry according to the installation manual.
