TERMINOLOGY (Description of Main Terms)

Scanning: The facsimile receiver picks up a facsimile signal from the air and reproduces it into pictures In reproduction, the recording head starts to print out a picture dot by dot from the left end of the facsimile paper towards the right end of the paper, wraps around to the left end of the paper from the right end, prints another line towards the right end from the left end, repeats these steps until the end of the signal comes This movement of the recording head is called "scanning."

CHAPTER1 GENERAL

1.1 Function (1)

(2)

The JAX-9A receives facsimile broadcasting signals (2 MHz to 25 MHz) including weather and marine charts and graphically prints them on thermal recording paper

With the JJC decoder (NWF-45), the JAX-9A can receive and print pay broadcasting signals (from the Kyodo News)

(To receive the pay broadcasting, you must make a contract with the Kyodo News Service and rent the IC decoder (NWF-45) from the Kyodo News

1.2 Features (i)

(2)

(3)

A variety of receiving methods

@ Automatic reception (AUTO)

The JAX-9A can be remotely controlled to automatically start up, set parameters, receive pictures, feed paper, and stop by remote signals sent from the broadcasting station However, only the half-tone recording is manually controlled

@ Manual reception (MANUAL)

In this mode, you can manually set the index of co-operation, the scanning speed, and the half-tone recording The JAX-9A automatically records and stops in this mode

Forced recording (REC)

This is an extensive function of the manual reception The JAX-9A can manually record while the JAX-9A is neither in the AUTO mode nor in the MANU mode (while broadcasting is in progress) In this mode, phase matching is done manually TheJAX-9A employs a unique method of terminating phase matching instantaneously

@ Program reception (Timer)

This function using the built-in timer enables unattended operation of the JAX-9A at the scheduled time points and in the programmed sequence when you program a channel start/stop time, a starting method, a reception frequency, and use/disuse of the halftone function

Half-tone recording with 16 gray tone patterns

This function supports 16 gray tone patterns (coarse and fine patterns) and very effective to print out clouds (photographed by a weather satellite)

Fine line compensating circuit

This unique circuit can clearly reproduce fine lines such as map lines and geographical lines (longitude and latitude lines)

For connection of the JIC decoder (NWF-45), the JAX-9A must be partially altered Take the steps shown below to connect the NWF-45 (For professional help, call your local JRC distributor.)

(1) Unit to be altered Control block CKK-523 (2) Procedure to alter

@ Remove the connector P502 (having no cable) from the connector J502 on the controller PCB

(printed circuit board)

Press the button of the facsimile unit and open up the top cover You can see a PCB having five connectors on it inside the facsimile unit Hold the left and right black ends of the rightmost blue connector and pull it out

CHAPTER 4 OPERATION

4.1 Setting Receiving Frequencies

The JAX-9A facsimile receiver can receive short-wave facsimile broadcastings (2 MHz to 25 MHz) Each broadcasting station broadcasts identical data on several channels So you can select a channel for optimum pictures Further the propagation of short waves will be greatly affected by environmental conditions such as receiving locations, days or nights, seasons, and so on Consequently, the optimum reception frequency will vary and you must reset the frequency

The JAX-9A has an Automatic Frequency Selection function to select a frequency for optimum picture reception among a group of broadcasting frequencies

4.1.1 Automatic frequency selection

The Automatic Frequency Selection function automatically selects a frequency for optimum picture reception among a group of facsimile broadcasting frequencies of a single broadcasting station that have been registered

If the reception status of a selected frequency becomes worse, this function automatically re-selects another frequency for optimum picture reception

To use this function, you must register all broadcasting frequencies of a single facsimile broadcasting station for frequency channels of a single group

(1) Frequency channel

A frequency channel is a channel to which a facsimile broadcasting frequency is registered (or

memorized)

One frequency channel has a maximum of nine frequencies The JAX-9A can have a maximum of 90 channels (10 groups)

(2) Group channel

A group channel is a representative frequency channel for each 9-channel group You cannot register any frequency

The JAX-9A has ten group channels and frequency channels related as shown below

Group channel Frequency channel

-27-OPERATION

(3) Setting procedure

Take the steps shown below to register all facsimile broadcasting frequencies of a single broadcasting station to frequency channels of a single group The example of registration below assumes

registration of frequencies to channel group 00 to automatically select the facsimile broadcasting of the JMH

@® Register a frequency of 3622.5 kHz to frequency channel 01 @ Register a frequency of 7305 kHz to frequency channel 02 @ Register a frequency of 9970 kHz to frequency channel 03 @® Register a frequency of 13597 kHz to frequency channel 04 © Register a frequency of 18220 kHz to frequency channel 05 © Register a frequency of 23522.9 to frequency channel 06

@ Leave the other frequency channels unregistered Just press the button for the frequency channels 07 to 09 to prevent registration of unwanted frequencies

e For registration of reception frequencies, see 4.1.3

e "JMH" is one of the codes for calling facsimile broadcasting stations in Japan (JMH, JMG, etc.)

(4)

Do not register frequencies of two different broadcasting stations to a single channel group If done, you may be able to receive the facsimile signals from the target station

Using the Automatic Frequency Selection function

Call a group channel (representative frequency channel) of a frequency group including the frequencies of a target facsimile broadcasting station For example, take the following steps to receive and record facsimile signals from the above JMH

@ Press the button then enter |0] [0] The Automatic Frequency Selection function starts to

select a frequency for optimum reception among frequencies of the channel group 00 @) When you want to use this function after the above operation, repeat the above step again

e This function is available when the receiver built in the JAX-9A is used

e Use this function at least one minute before the facsimile broadcasting starts because it takes a little time to automatically select a frequency

® The reception status of the selected frequency is not always the best because

@®) The aerial status (radio wave propagation status) of the selected frequency is not good @ The aerial status (radio wave propagation status) is good only while the automatic frequency

selection is made Or

@ The aerial status (radio wave propagation status) of the selected frequency becomes worse gradually

Trang 31

OPERATION

e This function is available to all four reception methods of the JAX-9A mode (AUTO, MANU, #REC

(Forced recording), and TIMER)

e This function works in the following cases:

@ When a group channel is called by the button and numeric keys

(@) When the power switch was turned off in the Automatic Frequency Selection mode and is turned on in the same mode

(3) When the radio propagation status of the reception frequency becomes worse gradually
