Setup Bluetooth Menu  

SIMRET 4000 

 maintains two Bluetooth Device Lists of up to 8 Bluetooth devices identified by their 

Bluetooth Addresses and their Friendly Names 

 

Bluetooth Search

: searches for local Bluetooth devices that are in the discoverable state. This 

takes about 30 seconds, but click at anytime to terminate. Results are shown as Friendly 
Names in the 

Devices Found

 table, see below. To be discovered, Bluetooth devices such as 

the printer or pedal pad must be switched on first. 

Devices found:

 shows the results of the last search (if available) as Friendly Names. Click on a 

name to add it to the BlueTooth Device Lists at the location following that of the device 
currently paired as the printer (see 

Warning

 below) and set the instrument  ready to pair with 

the new device as the printer. Alternatively, scroll to and click on 

Go back

 the end of the table 

to do nothing. 

 

Warning

:- this will overwrite the existing Bluetooth Device Address and Friendly Name at 

that location  

 

Make Discoverable:

 allow the 

SIMRET 

to be discovered by other Bluetooth devices. The 

passcode is 1234.
