Hybrid Scales – Part Wired / Part Wireless
Hybrid systems have 2 separate parts:
1. A pad control board under the tablet that powers the load cells
and sends the data to the tablet display. This is where the
cables are connected.
2. The tablet display. This connects to the pad control board via
Bluetooth® and can be removed and used wirelessly.
2 separate parts - both with separate ON switches
Tablet: Push the ON button on the bottom right side and hold for 3 seconds to
turn on the tablet and launch the operating system. After about 15 seconds the
home page will appear. IMPORTANT: WAIT FOR BLUETOOTH® ICON TO
APPEAR BEFORE LAUNCHING
COMPUTERSCALES XLI™ APP.
Tap the app icon on the Home Page to launch the ‘app’
COMPUTERSCALES XLI .
Pad Control Box: Now turn the Control Box ON . There is a small silver
button just below where the tablet ON switch is located. The LED light indicates
power is turned on. In a few seconds it will connect with the tablet and display your
weights. You are ready to go.
NOTE: If the tablet shuts down or goes into ‘sleep’ mode you will need to turn the Control Box back on.
To use the display wirelessly just remove the tablet from the holder by releasing the
spring loaded bracket. When reinstalling, be sure the ON switch is on the lower right.
If not, the display will be upside down.
Zero: Tap BEFORE putting car on scales. DON’T zero AFTER car is on scales.
Memory: Tap arrows (<& >) to select memory number. Tap Save to
Memory
to save current weights. See below to enter optional Memory
Name
and Notes . Memory weights are shown under current weights. If you
don’t want memory numbers to show on the display simply select Memory #0.
If the memory location already contains data a warning message will pop up. If
you do not want to overwrite the location choose
NO and tap arrows (<& >)
to select a different memory number.

COMPUTERSCALES XLI HYBRID VER 1.25

Note Taking: Tap arrows (<& >) to select memory number. Tap
Notes – Add/View Name Memory at the bottom right. A keyboard will
appear with text boxes at the top.
At the very top is the Memory number you selected for reference (in yellow).
Under that is a narrow text box called
Memory Name . Tap this box to enter.
An orange border will confirm the box is selected. This is where you will name
this Memory number – title, date, track, etc. – your choice. 15 characters
maximum. Naming the location is optional. The
Memory Name will display
on the main screen at the bottom.
Next below is the
Notes box. Tap on this box – orange border confirms the
box is selected. Assuming this is empty you can begin typing notes (it begins in
the middle of the screen). There is almost no limit to the notes and data you
can enter. If you fill the screen up it will scroll for more space. Use your fingers
or the stylus (the stylus will keep the tablet screen cleaner). To correct errors or
edit your notes tap the screen where you want to edit. A blue arrow will appear
to indicate your location. Back up (use the tablet back space button) and retype
as needed. If you want to start over hold your finger or stylus on the copy until
the entire word is highlighted. Then go to the top and tap Select All. Re-enter
notes. The original notes will be erased.
To take notes by voice go to the second box from the left at the bottom of the
keyboard. This should have a microphone icon (if it has anything else in this
box tap and hold – another box will appear above it with the microphone icon –
tap on that). When you tap this icon the keyboard will disappear and the
icon will appear in the center with “Speak Now” above it. Speak directly into
the tablet microphone at the bottom. Speak slowly and clearly. There should
not be any significant background noise. Your words will appear on the screen.
This is an Android® function and works well with some practice but is not
always perfect. Even if it gets a few words wrong you can edit to correct the
errors. This can still be faster than typing. This voice recognition improves with
use as the tablet ‘learns’ to understand you better.
To pause speaking tap the icon. It will change to black & white and “Tap to
speak” will appear. Tap again to resume speaking. Close the voice input box
with the keyboard icon (or X on some Android® versions) and the full keyboard
will reappear. If needed edit your voice notes and save.
When done tap
Save Name & Notes . The app will take you back to the
main screen. (10” tablet already shows the main screen so Save Notes button
just saves the file.

In the future to view these notes tap the arrows (<& >) to select the memory
number and tap the
Notes – Add/View Name Memory button again.
You can edit these notes at any time or you can erase them completely for
other future use. DX3 10” Hybrid systems have 50 Memory locations. DX2 7”

Note: While in this Note Taking screen you will still be able to see part of the
main screen in the background (except on 10” side-by-side note taking).
Refer to the Setup Screen section for instructions on saving your Memory and
Notes to file for transfer to your PC, spreadsheet or setup software. Save one
location or all as a group.
10” Tablet Side-by-Side Note Taking: (Shown on page 6) Note taking
screen and main application screen are shown side-by-side. Note taking
functions the same as the smaller tablet but offers the benefit of the side-by-
side display for you to easily keep track of everything on one screen and a
button to quickly erase your Notes and Memory Name and start over.

hours.
Replace control box batteries: The control box runs off separate
Alkaline batteries. Access is behind the control box and uses 3 “D” cell
batteries. Remove the 4 screws for access. These should last 120+ hours or
roughly 2 years. The LED on the control box changes to RED when low.
Re-pairing: The control box and tablet are connected wirelessly via
Bluetooth®. Occasionally the pairing between the two will be lost and you will
need to re-pair. This is a very simple process that takes less than a minute.
Refer to page 20 for pairing instructions.

Misc. (but important) Notes
Here are some messages that may come up from time to time:
The wording may vary slightly. Always answer YES. The wrong choice will
affect your system’s operation. This is part of the Android® OS Security System.
They should not come up often. If the tablet battery is low connect the charger.
General Precautions: ● Do not drop the tablet or pads (they have
electronics). ● Keep the entire system clean and dry. ● Do not expose to
excess heat or cold:32°F (0°C) to 120°F (38°C). ● Keep the tablet away from
strong magnetic fields (caster camber gauge?). ● Do not overload the pads
(confirm capacity). ● Clean the tablet as needed with a soft cloth only. Use no
cleaners or chemicals. ● Be cautious if you are doing anything in the Settings
section of the tablet OS (not part of the app). If you turn Bluetooth function off
or un-pair the control box the scales will not operate. Restoration is easy.
A screen saver has been pre-installed on the tablet display. This helps protect it
from scratches. Replace when needed. (When you first turn on the tablet the
model number will show so you can get the correct replacement.) Using the
included stylus helps this also.
Wireless range: This system uses the Bluetooth® wireless protocol. It
operates at a power level that does not require an FCC license. The practical
operating range is from 30’ to as much as 200’, depending on conditions. The
best range is indoors as the signals bounce off walls. The shortest range is out
in the open with nothing else around. Other cars around, machinery, shelving,
etc. can affect range also but it should never be less than about 30’.
To shut system down: Tablet – Push & HOLD ON for 3 seconds.
Display changes. Tap ‘Power Off’and then tap ‘OK’.If you don’t do this the
tablet battery may be low the next time.

Leave WiFi off unless you specifically need it: This choice
is accessed in the Settings section of the tablet OS (not the app). If WiFi is left
on the tablet battery life will be less before needing to be charged. Also if you
are in a WiFi hotspot and turn the tablet on it may attempt to upgrade the
Android® operating system to the latest version. This is an Android ® function.
You can allow the tablet to upgrade the operating system if you wish. In the
Settings section turn WiFi on. NOTE: When you update the OS you may need
to re-enter your SysID security number and/or re-pair the control box to the
tablet. If your system does not function after the update (
NO DATA ) see the
enclosed instructions for re-entering the SysID. This is simple and takes less
than 1 minute. When the OS update is done we recommend that you turn WiFi
off. This system operates on Bluetooth® and does not need WiFi in regular use.
Install Custom Car Display Icon
You can have a picture of YOUR car as the display icon: First send
us a high quality, high resolution picture of your car in a jpg or other image
format. An overhead shot is needed from straight above the car. This will
require shooting from a second story (or even a tree). Shots taken from a
ladder may not look as expected. Email us the picture to
[e-mail] with your contact info. We will drop out the
background, size the image to fit the screen and email it back to you. The image
will be named customcar.png. Do NOT re-name this as the tablet looks for this
name when selecting the custom car option.
NOTE: If the resolution of the picture is not high enough we may not be
able to create this custom icon. Take a picture at the largest size and
highest resolution. The cost for this service is $79.00 but may be waived.
Connect the tablet to your PC with a USB connector (at the bottom of the
tablet where the charger connects). Tablet must be powered on. Don’t open
the app at this time.
On the PC, browse to your ‘Computer’or ‘My Computer’folder. You will see
‘SM T210’or similar designation for the tablet. Double click on this to open and
then double click on Tablet.
Look for a folder named ‘Longacre’. If there is not one, right click to create one
and name it Longacre.
On your PC save the customcar.png icon file we email to you to your Desktop
or Documents folder and then drag and drop it into the Longacre folder on the
tablet.

Disconnect the USB cable and launch your COMPUTERSCALES XLi app.
Swipe to the setup page, scroll down to Car On Display and select Custom.
Swipe back to the main screen and your custom car icon will appear and
function just like the others. It will stay until you change it.
Simple Troubleshooting
Be sure the Bluetooth® icon shows before launching the app.
If you launch the app COMPUTERSCALES XLI™ before Bluetooth® is running
(shown by icon at top of device screen) Android® will ask you, “Do you want to
connect to this device?” Even if you answer “Yes” it may not connect, in which
case you may need to re-boot the app and/or the control box.
When you first turn on your system and launch the app if you have any connection
problems (
NO DATA on display and the control box LED is not flashing) first
reboot the control box . If this does not correct the issue reboot the app (off, then
back on). Close the app with the button and restart (no need to shut down the
tablet completely – just the app). This is rare.
In operation if you lose the connection (
NO DATA on display) reboot the control
box. This can happen if you get out of range with the tablet, then come back in
range. On rare occasions the wireless link will not immediately re-establish and
rebooting the control box resets the connection. This only takes a few seconds. See
main instructions for battery or power issues.
Troubleshooting Connection: ‘NO DATA’ indicates the tablet
is not receiving weights from the pad control box. First be sure the control box
is on, indicated by a green LED. If green LED is steady – not flashing – there is
no communication.
Possible solutions:
•First reboot the control box (turn off and back on).
•If it doesn’t start working in 5-10 seconds try rebooting the app. Do this by
tapping at the bottom right of the display. The Home Page comes up.
Tap the app icon to re-launch the app.
•If this doesn’t work (very rare) power down the tablet completely, shut off
the control box and start over. Even this takes less than 30 seconds.
Bluetooth® icon
Must be on before launching app. This takes
about 4 seconds after the Home page appears
when powering up the tablet.

COMPUTERSCALES XLI HYBRID VER 1.25
16
Coming out of ‘Sleep’ mode: If your tablet has been in ‘Sleep’
mode for more than an hour if may be necessary to reboot the control box to
reconnect. This is an Android® security function. If you get
‘NO DATA’ when
you take the tablet out of sleep simply turn off the control box, then right back
on. This will reset the wireless connection and restart communication. This only
takes a few seconds.
Shows ‘NO DATA’ and control box LED is flashing: If
you have updated your Android® OS and now the system doesn’t work re-enter
the SysID on the setup page. See instructions on page 17. Updating the OS can
sometimes delete the SysID. The control box is communicating with the tablet
but not the app.
‘Pairing’ the control box with the tablet: On rare
occurrences the connection between the control box and the tablet – ‘Pairing’
– will get broken. See instructions on page 20 for re-pairing. This is simple and
takes less than 2 minutes. This will be necessary if you change devices – from
the tablet to your Smartphone, for example.
Tablet battery: If your tablet will not turn on and you have had the
charger connected, try another charger and/or USB cable. Most chargers with
USB connections put out the same voltage and can be interchanged. If the
charger is functioning you can tap the ON button and a battery image will
appear and show the charge state. If it does not, the charger is probably not
functioning and the tablet will not operate.
Any other issues: If you are unable to get your system functioning
please contact the factory at 360 453-2030 M-F 6:30am to 4:00pm Pacific time.
VERY IMPORTANT: Please have a list of ALL symptoms available.
Service: If service is needed please call or email first for an RMA #. Be sure
to send the control box and the tablet. Don’t send the pads unless requested.
