ADVARSEL !
Lithiumbatteri – Eksplosionsfare ved fejlagtig håndtering.
Udskiftning må kun ske med batteri
af samme fabrikat og type.
Levér det brugte batteri tilbage til leverandoren.
(English)
Caution !
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type
recommended by the manufacturer.
Dispose of used batteries according to manufacturer’s instructions.
(Finnish)
VAROITUS
Paristo voi räjähtää, jos se on virheellisesti asennettu.
Vaihda paristo ainoastaan laitevalmistajan suosittelemaan
tyyppiin. Hävitä käytetty paristo valmistajan ohjeiden
mukaisesti.
(French)
ATTENTION
Il y a danger d’explosion s’ il y a remplacement incorrect
de la batterie. Remplacer uniquement avec une batterie du
même type ou d’un type équivalent recommandé par 
le constructeur.
Mettre au rebut les batteries usagées conformément aux
instructions du fabricant.
(Swedish)
VARNING

[8] SIMULATION
(Diagnostics, setting, adjustment value
input, data display)
1. Outline and purpose
There are following simulation functions to check the machine opera-
tions, troubleshoot, find causes, make various settings, improves ad-
justment work speeds and serviceability. 
1) Various adjustments
2) Specification and function setting
3) Trouble cancel
4) Operation check
5) Counters check, setting, clear
6) Machine operation conditions (operation history) data check, clear
7) Transmission of various data (adjustment, setting, operations,
counter, etc.)
The operating procedures and displays slightly differ from the form of
the machine operation panel.
The typical forms are as follows:
1) Code system: Values input and mode selection are made with the
10-key pad and various function keys. 
2) Switch system: Simulation mode selection is made by combina-
tion of switch setting. 
3) Values and mode selection is made with various function keys. As
a special one, a jumper wire is used to connect the check points
on the PWB to select the desired mode. 
2. Code system simulation 
A. Operating procedures and operations
Entering the simulation mode
1) Program (P) key 
 Interrupt key 
 Clear key 
 Interrupt key
(The machine enters the standby mode for the simulation main
code.)
2) Enter the main code with 10-key pad. 
 Press START key.
3) Enter the sub code of with 10-keypad. 
 Press START key.
4) Select the mode and the item with the 1-key pad and the function
key. 
5) The machine enters the selected mode.
To start the simulation, press the START key or the function key.
To cancel the current simulation mode and to change the main
code and the sub code, press the interrupt key. 
The simulation mode is canceled and the machine returns to the
normal operation mode. 
1) Press the all clear key. 
SIM 46-12, 13, 14, 15, 16, SIM66 and SIM68 are provided only for
Japan models (FAX mode/ASK/IrDA).
