1、Instruction Manual for Model AR1OOO Wide Range Portable Monitar Receiver a.eD.fR. Ptb. 2-6-4 Misuji, Taito-Ku, Misuji, Tokyo, Japan fione: (03) 865 1681, Fax: (03) 865 1697 Controls and function 1 . Antenna Connector. This is a standard BNC high frequency connector mounted on the top face of receive

2、r. 2. VOL (volume) control. This is the inner knob of the concentric controls on the top face of the receiver, and is used to set the desired level of audio from the receiver. In its fully anti-clockwise position, it turns off the power to the receiver. 3. 8QL (squelch) control. The outer knob of th

3、e concentric controls, the squelch control is provided to eliminate the background noise on unoccupied frequencies, and also to enable the receiver to decide whether or not to stop on a frequency when searching or scanning. Turn the SQL control from the fully anti-clockwise position until the backgr

4、ound noise just disappears. This is the most sensitive setting for the SQL. It is usually preferable to advance the squelch control little way further clockwise than the most sensitive setting to avoid inadvertent stopping on noise or very weak signals. 4 . ATT (attenuator) switch. For most uses, th

5、e DX or long distance setting is used for most sensitive condition for the receiver. However, when operating the ARlOOO in the presence of very strong signals such as those from TV stations or FM broadcast transmitters, some interference effects may be apparent. This can take the form of increase le

6、vels of background noise, or spitting noises occasionally heard on peaks of modulation from the interfering source, or strange spurious signals generated by intermodulation between the strong signals. The cure of most of these effects is the use of the ATT switch in the LOCAL position. 5. UP/DOWN kn

7、ob. This is-the tuning knob. For a full description of the use of the knob. 6. EAR (earphone or external speaker). This is used for connection of either the earphone supplied, or an external headset or loudspeaker. When a plug is inserted into this jack, the internal speaker of the ARlOOO is automat

8、ically disconnected. The impedance of the external load should be 8 ohms or greater. 6 4, 5 MANUAL SCAN SEARCH PROO WFM AM LOUT HOLD DEIAY BATT Display Panel showing a l l legends.

9、nd form. CHG. This concentric socket is mounted on the side of the case and is used for connection of the mains charger supplied, or the DC power cord supplied, or any suitable 11 to 14 volt DC supply. Xeyboard controls 1. First of all we have the numerical keys from 0 to 9, plus the decimal point (

10、.). These are used for entering frequency, frequency step size, memory channel number, bank number, and so on. The same keys are used in the bank select mode, in which case the numbers 0 to 9 correspond to the frequency bands listed in the operating paragraph of this handbook. The bank designations

11、are show on the lower side of each number key. 2. CLEAR.(.) Press once to enter a decimal point when entering frequency information. Press twice to clear an incorrect entry. 3. ENTER key. Used to enter frequency after selection by the keypad, or to complete many memory changes or operations. 4. SEAR

12、CH key. Used to start the frequency search action of the receiver; also used to manually advance frequency after the search has stopped. 5 . SCAN key. Used to start the memory scanning system of the receiver; also used to manually advance the memory channels when the scan has stopped. 6. MANUAL key.

13、 Used to engage the manual mode of receiver control, 9 at is when the user wishes to directly enter a frequency of interest to the receiver, or directly select any memory channel. 7. PROG key. Used in programming search frequency limits. 8 . LIMIT key. Used in conjunction with the PROG key in fixing

14、 search band limits. INC key. Used when entering the desired frequency increments or Ls , from 5KHz to 995KHz. 10. Bank key. Used to select the desired memory bank or search bank from 0 to 9 when scanning or searching. Page 2 11. AM/FM key. Selects either mode as required. 12. W-FM key. Selects eith

15、er W(wide)FM or narrow FM as required. 13. LOCKOUT key. Press once to lockout the channel or frequency show on the display. 14. DELAY/HOLD key. Press to change from DELAY to HOLD and back again sequentially in both search and scan mode. When HOLD is shown on the display, the scan or search stops on

16、a busy channel and remains there even after the signal has gone off. When I1DELAY is shown on the display, the scan or each stops on a busy channel, but then automatically resumes the search or scan approximately 2 seconds aft the signal has gone off. 15. Down arrow key Initially, the search or scan

17、 action is always from lower frequencies to hiqher, or lower memory channels to higher. If when searching or scanning, the down arrow key is pressed, the search or scan stops, and the down arrow mark is shown on the display. Subsequent short press of the down arrow key will step the scan or search d

18、ownwards. If the down arrow key is held pressed for more than about one seconds, the scan or search will re-start, but in the downwards direction. 16. KEY LOCK key. Press this key to disable all keyboard function. Press again to restore all function to normal. This key is used to prevent accidental

19、mis-operating or changes of frequency when the receiver is being carried around but still in use, for example at air displays. 17. LIGHT key. Pressed momentarily, this will illuminate the display for approximately six seconds, after which the lamp will automatically be extinguished. Manual Oeration
