5.2.6 Full Parameter Access

To access all features provided by the Echotel.

Description of all parameters can be found under the chapter “Parameter” (Chapter 6.).

Keys

Function

ENTER 

E

 + NEXT 

(press for 3 seconds)

Enter or exit Full Parameter Access programming mode.

In this programming mode, the display will indicate:

yy is the Parameter Address
xxxx is the Parameter Value

Note: Measuring is going on during programming in accordance with the old parameter set. New parameter set will be valid
after returning to measurement from programming mode.

Steps and indications of the Full Parameter Access programming mode

 

pressing 

Keys

while

 Parameter Address is blinking

 

while 

Parameter Value is blinking

ENTER 

E

Go to the Parameter Value

Save the modification of the Parameter Value and return to the
Parameter Address

NEXT 

 + UP 

Cancel all modifications of the actual
programming phase. Pressing for 3 secs is
required while CANCEL will be displayed
for warning

Neglect the modification of the Parameter Value.
and return to the Parameter Address without saving the
modifications

NEXT 

 + DOWN 

Reset entire device to Factory Default.
Since this action will reset all parameters,
“LOAD” will appear on the display:
- to confirm, press ENTER
- to escape, press any other key
- Exception: clearing TOT 1 (See at P77)
