BLUETOOTH:

 The Simret 4000

, Printer & Pedal Pad

 are equipped with Bluetooth to allow them 

to communicate wirelessly at distances of up to 10 metres. New instruments are preconfigured 
to automatically pair with the printer and pedal pad supplied. The user can also set SIMRET

 

to pair with additional devices (see 

Setup Bluetooth 

menu). 

When the Bluetooth feature is turned ON, the instrument will pair automatically. The 

instrument will decide if it needs to pair for 

Brake Testing

 or for 

Printing

 and the appropriate 

warning message will appear on the screen. Preferably, make sure the appropriate remote 

device is switched on at this time. However, SIMRET will continue trying to pair until the 

device is switched on and pairing is successful. Successful pairing normally takes just a few 

seconds, although if many discoverable Bluetooth or WiFi devices are in range it may take a 

little longer. If the device will not pair, just 

single click

 to try again or 

hold down

 and release 

to abandon and investigate. 

To pair with the 

Printer

, first make sure the printer is switched-on by pressing its 

 

>>

 button, 

a green light appears on the printer (no green light means its battery is flat). The 

Printer

 will 

then stay on and paired until the SIMRET is switched off or is paired with the 

Pedal Pad

. The 

Printer

 will switch itself off after one minute if it can’t pair. 

To pair with the 

Pedal Pad

, first switch it on by pressing firmly with your foot for about 1 

second then releasing. The yellow light will turn off when pairing is successful. The pedal 

will stay active and paired until the 

SIMRET

 is switched-off or is paired with the 

Printer

.  

Bluetooth devices are identified by their unique Bluetooth Address (a 12 digit number) and a 

“Friendly” name. To aid identification, all devices are marked with their Bluetooth friendly 

names. The friendly name will usually incorporate the serial number of the device.  

If Bluetooth is fitted, then at switch-on the instrument will make itself discoverable to other 

Bluetooth devices, such as a Bluetooth laptop, PC or iPhone, for uploading etc. After printing 

or brake testing you can make the instrument discoverable again by double clicking on the 

Main Menu

. The Bluetooth passcode is 1234. 

STORAGE AND CHARGING:

 Always return the Simret 4000 to its protective Pelicase after use, 

store accessories in the compartment below. Connect one of the curly captive charging leads 
to the underside of the 

Modulo

, connect the second curly lead to the 

PFT
