2.0 INTRODUCTION
2.1 Battery Care
The OMNIA-6 instrument uses a Ni MH rechargeable battery and includes smart charging techniques to maximize battery life. For recharging the internal battery, Ro.Ve.R. Laboratories S.p.A. includes a single-unit battery charger as a standard accessory.
Charge the battery for a minimum of four hours before initial use. The fastest battery recharge time is obtained with the OMNIA-6 turned off.
When the battery charge is low, an audible warning is heard and a low battery message appears on the display.
2.2 Power On
Turn on the meter by momentarily pressing the power/reset key.
2.3 Power Off
Turn off the meter by pressing and holding the power/reset key for three seconds. Pressing and
holding
for ten seconds resets the meter and restores normal operation.
2.4 General Instructions for Navigating On-Screen Selections
The basis for screen navigation is the position of the selector tool (*). The action necessary to move the indicator depends on whether Text or Graphic screens are displayed.
On menu screens, using and keys move the selector tool (*) from one item to the next.
Figure 1: Text Screen Navigation Example.
Omnia-6 User’s Guide Draft Version

For graphic screens, the , and keys move the selector tool (*) clockwise and anti-clockwise, respectively, to items with more than one user selection. Note that the selector tool rotation is relative to its original starting position and may sometimes appear to move in the wrong direction.
Figure 2: Graphic Screen Navigation.
With the selector tool (*) beside it, the user can press
and update the values on the selected item. A
solid arrow will appear beside the current value. Pressing the arrow keys (
, ) will then allow the
user to change the value. Pressing
again will keep the current value and deactivate the ability to
update the item. The solid arrow indicator is replaced by the selector tool (*).

25.0 HOW TO MANUALLY CREATE A CUSTOM PLAN
25.1 How to copy Source Plan to Destination Plan
Press and hold the for 2 seconds until the SELECT FILE PLAN title is displayed. This screen allows the user to copy a SOURCE plan to a DESTINation plan. The SOURCE plans available are a set of default MASTER PLANS pre-loaded into the device (i.e. Euro/IND, UK/HK etc.) and any custom plans already present in the device. The DESTINation custom plans are labelled at the factory as PLAN 1, 2, 3, 4, 5, and 6.
Press
Figure 35: Select Source Plan.
It is possible to insert the channel search mode by choosing either “MANUAL” or “AUTO”. In “MANUAL” each channel is inserted manually, whereas in “AUTO” all the channels with a level above the set threshold “THRESH” are inserted automatically.
Continue to press until the plan desired is present. Once a SOURCE plan selection has been made,
press
and press to go to the DESTINATion selection.

25.2 How to edit Channel Plan
The user can modify existing channels, delete, or adding channels manually. Use the standard navigation techniques described in the Introduction to select channels, types, frequencies, symbol rates (for digital channels), and level offset (for scrambled channels).
Figure 37: Edit Channel Plan Screen.
25.3 Modifying Channels
If the proper channel format is selected (Standard), very little modification is required to core analogue channels included in the plan, except for additional offsets from standard or scrambled channels. The main adjustment required to be made to the plan is to properly set any digital channels existing in the cable system.
25.4 Selecting Channels
Use standard navigation to navigate to the channel required for modification as shown below.
Figure 38: Select Channel.
Continue pressing
until the desired channel is reached, then press to complete the channel
selection process. Step through available options described below to set channel parameters.

25.6 Selecting frequencies
Use standard navigation to select the FREQ item on the screen. Press and hold
or to quickly change to the frequency required. As you get closer to the required frequency, press the individual keys one at a time to better control the frequency update. If the correct frequency for a video carrier or the centre frequency for a digital carrier is not correct, the measurements made by the unit may be incorrect or function improperly.
Figure 40: Select Frequency.
25.7 Symbol Rate
When a digital type is selected (e.g. QAM256B, QAM64B), the symbol rate item appears on the screen. Use
standard navigation to select the Symbol Rate and modify using
or . The correct symbol rate must be entered in order for the digital measurements to function correctly. Typical symbol rates for a QAM64B and QAM256B are 5.056 MS/sec and 5.361 MS/sec respectively.

25.8 Level Offset
When a channel is set as type SCRAMB, the Offset item appears on the screen. This offset will be applied to each video carrier measurement made on the channel. Use standard navigation to select the Offset item
and adjust accordingly using
or . Options range from –10.0 to 10.0 dB.

25.9 Deleting Channels
Using standard navigation, select the channel you want to delete. Move the selector tool(*) down to the
DELETE item. Press
. A WAIT message will appear, then the channel will no longer be on the list. If you are deleting a block of channels, start with the channel with the highest frequency first to facilitate the deleting process.
Figure 44: Delete Channel.
25.10 Adding Channels
You can only add a channel in the custom plan if the 6 MHz slot that the channel would fall in does not have an allocation in the current plan. For example, you have channels 79 and 81 allocated, but channel 80 is not defined. If that is the case, using standard navigation, change the channel to the adjacent channel below or
above the channel to be added. Now change the frequency to the desired frequency using
or . As the frequency moves into the empty 6 MHz slot, the REPLACE and DELETE items will disappear and the ADD will appear. A channel name will automatically be assigned depending on the type of channel (starts at C 1 for analogue, Q1 for QAM channel, D 1 for any data channels, and FM 1 for an FM channel). This channel name can not be altered. Once all the channel parameters have been set, move the selector tool (*)
to the ADD item and press
.
