T-STAT 2.0 User Manual 

Instructions for Use of On-Call via Wi-Fi 

 

 
 
 
 

To set up On-Call access using Wi-Fi connections available in the vicinity, follow the instructions 
provided below: 

 

1.

 

Power up the T2 and wait for the self-test to finish its checklist. 

 

2.

 

At the back of the machine, there will be a terminator attached to the body of the 
T2. Unscrew the terminator and connect the antenna provided with the T2. (Refer to 
image below) 

 

 

3.

 

Turn the antenna until it is pointing upwards. 

 
 
 
 
 
 
 
 
 
 
 

4.

 

On the home screen, click on 

OPTIONS

 In the following page, there will be a number 

of options on the left panel. 

 

5.

 

Click on the button that says 

ONCALL ACCESS

 This will be the 4th from the top. 

 

CAUTION: 

Do not touch or move antenna while the unit is transmitting or 

receiving 

CAUTION: 

Do not operate the radio or attempt to transmit data unless the 

antenna is connected; this behavior may cause damage to the radio. 

WARNING: Do not engage Wi-Fi or use cell modems in areas where 
emissions could interfere with critical wireless monitors. Follow hospital 
policy.
