I. Estimation procedure with the chart 4-4-4a (for cylindrical obstacles)

i) Estimate the distance (R) from the obstacle; R (m) ii) Estimate the effective diameter (d) of the obstacle; d (m) iii) Read off the loss (LB) in the Chart 4-4-4a; LB (dB) iv) Determine whether the loss (LB) is allowable.

4-6 Countermeasure

If the equipment does not operate normally even following procedure is performed, consult JRC service agent. Take care not to touch any parts on PC board.

Abnormal operation of IME In case of the heavy fluctuation of the voltage or frequency of the power source, or thunderbolt

and etc., IME may not operate normally. In this case, try following procedure (a). And try procedure (b) when procedure (a) did not work.

(a) Set POWER switch to OFF, and confirm all of the LED lamps are lights out (it will takes approximately 3 minutes) and set to ON again.

(b) Press RESET button in the IME panel by the tip of narrow object (like extended clip,φ0.5mm). Push until you feel the object clicks. (refer fig. 4-6)

Five lamps (POWER lamp to RECEIVE lamp) lights in order, and starts blinking (it will takes approximately 10 seconds). Turn on POWER switch with confirming these lamps are blinking.

JUE-95LT may not reboot due to short-circuit of RESET button, if this button is pressed so strongly.

The data, which are received message, call logging history and alarm history, memorized in IME are cleared when RESET button is pushed. Saving important data to Floppy-Disk or USB Flash Memory is highly recommended (Prepare optional DTE, Floppy-Disk Drive (for DTE (NDZ-127C1)), and JUE-85 instruction manual).

Fig. 4-6 IME resetting

Procedure (b)

Push the RESET Button with a stick of wire like extended clip. The depth of the hole is approximately 1cm. So, use the wire 2cm or more.

Procedure (a)

Set POWER switch to OFF and set to ON again.

4-7 After service

4-7-1 About the longevity of the articles of consumption (exchange time) Contact the dealer from which you purchased the device or one of our marketing offices, when ALM lamp of IME lights, or blinks with 1-second cycle (Life of longevity of the Lithium is approximately 10 years, however it might be shorten depend on the customer’s usage condition. There is no influence in other telecommunication functions though the reception message and the call log, etc. cannot be preserved in the power discontinuity, when the capacity of the lithium battery is lost.

DANGER

The lithium battery is built into JUE-95LT (EME). Do not short-circuited of the terminal, do not give the high impact, and wet it to water. There is danger of exploding.

4-7-2 When ordering repair

When a failure has been detected, check it according to the Trouble shooting described in this book. When abnormalities are still accepted, stop operation and contact the dealer or agent from which you purchased the device or one of our branches, marketing offices, and representative offices.
