From then on this causes the RLT-50 to ignore the "zero" user bit information from the EVO-9800 and respond to
preset information from the RLT-50 front panel USER BITS SET switch.
When the user bits preset mode is first entered, the left most user bit on the display "flashes" between 0 and 8 about
once per second to indicate the selected user bit character. The front panel LED also flashes at the same rate.
Next, momentarily actuating USER BITS SET causes the selected user bit character to count up in hexadecimal
fashion from 0-9, then A-F, then repeat. When the desired number is set, momentarily switch to SEL to select the
next user bit digit. Repeat this process until all digits have been selected and no user bit characters are flashing.

USING THE RLT-50 IN THE FIELD
8.1 Operating From Battery Power
You can operate your RLT-50 from battery power in order to use it in the field.
The RLT-50 operates from 9 to 13.5 volts DC. In general it is recommended operating the RLT-50 from 12-volts
DC, obtained either from a conventional 12-volt video camera battery, or from a battery pack consisting of eight 1.5
volt cells. Either Alkaline or rechargeable Nicad may be used.
You can make a 12-volt battery pack from an eight cell AA battery holder (or two four cell holders), a length of two-
conductor wire, and a 3.5MM mini phone plug, all obtainable from local electronics supply stores such as Radio
Shack. You can also use a single pack of six cells to provide 9-volts, or a single 9-volt battery, but the operating
times will be considerably lower.
HORITA offers the BP-50 battery pack as an economical and convenient means of operating your RLT-50 from
battery power. The BP-50 consists of eight rechargeable AA sized batteries, battery holder, power cable, heavy duty
cloth case with nylon strap, and convenient wall-type overnight recharger with LED.
The BP-50 will typically operate the RLT-50 for 3-to-4 hours.

9.3 Troubleshooting
The following provides a list of the most common items to check if you are having trouble with your RLT-50.
9.4 General
If you suspect your RLT-50 is not operating properly, check the following first:
a. Make sure the video input to the RLT-50 is not "double terminated", that is, there are not two video
terminations on the video input and/or output line from other recorders, monitors, etc.
b. Check all coaxial cables in signal path for opens or shorts.
c. Check for proper installation of the 9-Pin communications cable between RLT-50 and EVO-9800.
d. If using an AC power adapter different from the one supplied with the RLT-50, make sure it supplies the
RLT-50 with at least 9-volts (maximum of 12-volts) when the RLT-50 is switched on.
e. Use the RLT-50 flashing LED indications to help determine presence of video, EVO-9800
communications, etc, as previously described.
