1. INTRODUCTION
Thank you for purchasing the Renaissance. You can say this watch is truly special, because it was
developed by a small international team of enthusiasts, including myself, from the idea to its
perfection. Of course, that was a challenge, but also a very beautiful process. I hope you will enjoy
using it as much as we did developing it.
Yours,
Dietmar Litschel
2. PACKAGE CONTENTS
The package of the Renaissance contains, besides the watch itself:
-Micro-USB charging cradle
-USB to micro-USB cable
-USB power supply
-Printed user manual
-Acoustic instructions and PC-Software on the mini CD
3. DEVICE DESCRIPTION
Renaissance is primarily a conventional wristwatch, which reliably indicates time and date.
But its appearance is not conventional at all. On the top side, where you would normally expect a
display or a dial, two engravings can be felt. The narrow lettering RENAISSANCE, and the circular logo
of Litschel Design. You won’t find a display or clock hands on Renaissance, because it gives all
information via acoustic signals or using vibrations.
Before you continue any further, carefully take your Renaissance out of the box and place it in front
of you. The metallic part of the watch should be facing upwards and the side of the watch with 1
false button and 2 regular buttons should be pointing to your right side.
3.1 KEYS DESCRIPTION
Renaissance has 4 buttons located on the narrow side of the watch and they are arranged in a
clockwise order. On the top right side (at “one o’clock”) you will find Button 1. The false Button is
exactly on the right (at three “o’clock”). On the bottom right side (at “five o’clock”) is the Button 2.

5
Button 3 is on the bottom left side (at “seven o’clock”) and Button 4 is on the top left side (at “eleven
o’clock”).
4. FIRST STEPS
After unpacking the watch, please remove the protective foil which covers the face. Although
Renaissance is charged before shipping, we recommend to fully charge the battery before first use.
To do so use the micro-USB-cable and connect it to a plug socket or to your computer.
The Renaissance is set to the date and time in the distributor’s/customer’s time zone. You can also
let the software synchronize your watch with your computer by installing the Renaissance sync
software and connecting your Renaissance to it via cradle. You can also change date and time
manually, for that please take a look at the "Standard operation mode- Settings" section.
4.1 BATTERY CHARGING
Renaissance is powered by a rechargeable battery. To charge the battery of your Renaissance use the
supplied charging cradle. Open the cradle by pressing the release button on the opposite side of the
micro-USB socket. Once the cradle is opened, place the watch with the metallic engraved side facing
up and the tactile marking (false button) close to the opening knob in the charging station. Only
when the watch is correctly placed in the charging station, the hinge can be closed. Plug the smaller
end of the micro-USB cable into the socket on the opposite side of the opening knob.
Now the charging station needs to be powered. You can plug the larger end of the micro-USB cable
into the supplied USB charger, any other standard USB charger or into a computer with a USB
interface.
At both events, “Charging started” and “Charging finished”, the user is notified with the following
signals: “Charging started” and “Charging finished”. If the battery is completely uncharged, charging
time is approximately 2 hours with the supplied USB charger.
Note: Depending on the USB port of your computer, different power output
may be available for charging. The watch will always be synchronized when
charging via computer, if the supplied software is installed. Regularly charge
the battery to make sure you do not lose any data or settings.

6
Note: You can also check the charging status, while the watch is in the charging cradle. By pressing
the key combination Button 2 and Button 4 once briefly. Renaissance will output the signal “Charging
started”, if it is still in progress or the signal “Charging finished”, when the charging cycle is complete.
Note: To extend battery life it should not remain discharged for longer than 6 months.
4.2 BATTERY LEVEL INDICATION
To retrieve the remaining charge level, press the key combination Button 2 and Button 4 once briefly.
The battery level is indicated by values 10 (fully charged) to 1 (battery almost empty).

5. OUTPUT SYSTEM
Renaissance works with a system of signals representing numerical values and sequences of signals
to display more information. All signals can be displayed optionally as vibrations, sounds or both.
Every numerical value and information is represented by a unique sequence of signals.
Sequences can contain 6 types of signals:
- The wave signal
- The short signal
- The long signal
- The very long signal (only used for charging purpose)
- The very long wave signal (only used for medication reminder or stop watch application)
- The click signal (only used for manual settings)
5.1 SHOWING NUMBERS
When displaying numbers, every signal has a value assigned to it:
Wave signal represents the number 0
Short signal represents the number 1
Long signal represents the number 4
Digits can be calculated as a sum of values.
For example:
Number 6: 1 long signal, 2 short signals (4 + 1 + 1)
Number 9: 2 long signals, 1 short signal (4 + 4 + 1)

7
Note: If a sequence of signals represents a number, the long signals will be displayed first, followed
by the short ones.
5.2 MULTI-DIGIT NUMBERS
Renaissance displays, except in Easy Mode, all numbers as double digit values. They are displayed as
tens digits followed by a longer pause and then ones digits. If the value is less than 10, the first digit is
represented by number 0 (wave signal).
For example:
08: wave signal, longer pause, two long signals
10: short signal, longer pause, wave signal
16: short signal, longer pause, long signal, two short signals
23: 2 short signals, longer pause, three short signals
This way Renaissance can display numbers from 0 to 99.
Please note: In the standard mode, time is specified in 24 hour format.
Easy mode uses a 12 hour format.
5.3 SHOWING SIGNALS
Additional to the numeric values, Renaissance uses other signals for giving more information. These
signals are listed below:
ON: 1 short signal
OFF: 1 wave signal
Charging started: 1 short signal, 1 very long signal, 1 short signal
Charging finished: 1 short signal, 1 very long signal, 2 short signals
Error: 1 short signal, 3 long signals (with falling frequency for buzzer
output)
YES: 1 long signal, 1 short signal, 1 long signal, 1 short signal
NO: 1 short signal, 1 long signal, 1 short signal, 1 long signal
Confirmation: 1 long signal
Alarm ring: 3 wave signals
Snoozed alarm ring: 3 wave signals, 1 short signal, 1 long signal
Medication alarm ring: 1 very long wave signal, followed by the number of the alarm
which is ringing
Countdown ring: 1 very long wave signal
SOS ring: 3 short signals, 3 long signals, 3 short signals
In Wireless Link Modus: (only for Renaissance +)
Search for wireless link devices: sequence of single short signals
Connecting with wireless devices: sequence of double short signals
Connection established: Yes signal

8
Connection separated: No signal
Value received: 4 short signals, 1 long signal, 4 short signals
(with rising and falling frequency for buzzer output)
6. OUTPUT MODES
Renaissance has 3 output modes:
-Vibrations-only mode (value 0)
-Acoustic-only mode (value 1)
-Combined mode (value 2)
You can check the current mode by pressing the key combination Button 2 and Button 4 twice
briefly.
6.1 VIBRATIONS-ONLY MODE
The first mode is the vibration mode. Signals are emitted only via vibrations. This mode is particularly
suitable for deafblind users or in a noisy environment. It is also a very discrete alternative for
someone who wishes to use Renaissance quietly.
6.2 ACOUSTIC-ONLY MODE
The second mode is the acoustic mode. Signals are emitted only via beeps. Sequences for numbers
and information are exactly the same, but different frequencies will help to distinguish the
sequences easier. Using acoustic signals only, slightly increases the battery life compared to the
combined mode.
6.3 COMBINED MODE
The third mode is the combined mode. Both, vibrations and acoustic signals are active.
Note: This is the default mode for the Renaissance.
6.4 OUTPUT MODE CHECKING AND SETTING
To verify which output mode is activated, briefly press the key combination Button 2 and Button 4
twice. Default setting is the combination mode, in that case the Renaissance will announce, that the
value is 2 (2 short signals).
To set the output mode, follow the steps 1 - 4:
1. First retrieve the current value of the setting you want to change by pressing the key
combination Button 2 and Button 4 twice briefly.

9
2. Press and hold the key combination Button 1 and Button 3, until the Renaissance emits a
confirming signal, to activate setting mode.
3. Now press Button 2 to reach the desired setting. By activating the setting mode the value
is set to 0. Every time Button 2 is pressed, the setting increases by 1. Change new setting
to 0 for vibrations-only mode, to 1 for acoustic-only mode and to 2 for the combined
mode. Any other value is invalid and will not be accepted.
4. Confirm the changed value by pressing the key combination Button 1 and Button 3 once
briefly. If the changes are done correctly, you will get the “YES”-signal. Invalid entries or
inactivity timeout (after 12 seconds) will be confirmed with a “NO”-signal and the old
value of the setting will be kept.

6.5 OUTPUT MODE SPEED CHECKING AND SETTING
Renaissance offers the possibility to choose among 7 different speed levels at which the signals are
displayed. Level 0 is the slowest and level 6 is the fastest.
To verify to which value the output speed is set, briefly press key combination Button 2 and Button 4
three times. The default setting of output speed is 3, so in that case Renaissance will tell the value is
3 (3 short signals).
To set the output speed, proceed as follows:
1. First retrieve the current value of the setting you want to change, by pressing the key
combination Button 2 and Button 4 three times briefly.
2. Press and hold key combination Button 1 and Button 3, until Renaissance emits a confirming
signal, to switch to the setting mode.
3. Now keep pressing Button 2 as many times to increase the setting to the new desired value. At
the start of the setting mode the value is set to 0. Each time you press Button 2, the setting
increases by 1. You can choose the new value from 0, which is the slowest setting, fit for
beginners, up to the fastest value 6, which would be appreciated by the advanced users. The
default value is 3. Any other value is invalid and will not be accepted.
4. Confirm the changed value by pressing the key combination Button 1 and Button 3 once
briefly. If the changes are done correctly, you will get the “YES”-signal. Invalid entries or
inactivity timeout will be confirmed with a “NO”-signal and the old value of the setting will be
kept.
