Hands-On Call Usage

The Hands-on Call feature is a unique
feature which provides a private call
experience. It is achieved by using a
directional speaker located at the bottom of
the wrist. The speaker projects the sound
from the watch strap when the user’s palm is
held to his/her ear. The palm redirects the
sound to the ear. Follow the steps below to
get the best experience.

Run the HOT Watch app in the Android
or iPhone or Windows phone. The app
opens the data connection (SPP).

● Wear the watch on
your wrist, close to
your palm. So that the
speaker is closer to
palm.

● Cusp the palm over the
ear. Make sure that
your palm is not
touching the ear:
otherwise the sound
will be blocked.

Energy Optimization

The HOT Watch is designed for maximum
energy efficiency. The watch defaults to the
energy saver mode. The Energy Saver or
Normal mode can be selected in the Settings
screens. Below are the differences between
the Energy Saver and Normal mode.

When the charger cable is connected

to a power source, make sure that the magnetic
side is not close to any metal surfaces. While teeth
are provided to prevent a short circuit on the
connector, the angular contact of the connector can
still create a short circuit.

● At Midnight 12 , HOTWatch
connections are cleaned up.

Phone Switching

When making or receiving a call from the watch, the
call stays on the watch. It can be transferred to the
phone by tapping on the headset button on the
phone. When making a call from the phone, the
default behavior of the phone is to push the call to a
Bluetooth device (HOT Watch in this case), but the
watch pushes the call back to phone (as user is not
using watch to dial-out). This will make sure that the
call will stay on the phone when the call is made
from or received from the phone. However, some
Android phones do not work well with this call
pushback. They tend to push the call back to watch.
This can cause automatic call switch to watch

during a normal phone call. To overcome this
problem, a special setting “EnbleBtOff” is provided
on the watch’s Settings screen to switch off the
Bluetooth (only call audio - HFP) when a call is
made from the phone. The HFP is enabled again
when the call is made from the watch or when a
new call comes in. Make this setting On to
prevent call switching. When this option is
enabled, the HFP Bluetooth icon is changed from
signal level to BT icon when HFP is kept in
disconnected state.

Bluetooth Icons

The HOT Smart Watch uses a dual mode
Bluetooth device with Bluetooth Classic (2.1) and
Bluetooth Low Energy (BLE, 4.0) in one device.
The Classic Bluetooth is used for call audio, data
connection, and phonebook access and music
control. BLE is used for data connection on the
supported iOS phones (available only with iPhone
4S, iOS 7 and above). The table below lists the
Bluetooth profiles supported by the watch.

The safest recovery at this time is to switch off
Bluetooth and switch it back on in Bluetooth menu
in the watch. In this condition it may help in
switching Bluetooth off and on in the phone also.

Notifications

HOTWatch supports SMS, Email, Facebook,
Twitter and other notifications.

In Android phone, the HOTWatch Application
forwards phone notifications to watch. By default,
Email, Facebook, Twitter, WhatsApp and WeChat
apps are enabled. The user can go to Settings and
enable other apps for global notifications. The
notification character size limit is 380 for Android.
The user can respond to SMS notifications from
the watch.

In iPhone, the HOTWatch receives notifications via
Bluetooth Low Energy (BLE) with GATT-ANCS
profile. Once the BLE is connected, these

When HFP is connected, Signal level is displayed
and when HFP is disconnected BT icon is
displayed. The Signal level and the battery level is
updated every 5 minutes. If any profile is
disconnected, touching this icon will try to
re-connect to that profile. If the re-connection fails,
the second touch will reset the Bluetooth.

“BattLow” is displayed, when battery level is at a
critical stage. Bluetooth is turned Off at this level.

Bluetooth Connection Issues

When Bluetooth connection is lost, watch tries to
reconnect automatically. In case it is not
successful, user can manually reconnect by
tapping the Bluetooth icon in main watchface
screen or tapping Reconnect in Bluetooth menu. If
connection fails first time, tap on the icon again
after the status message on this screen. Watch will
reset and connect Bluetooth in clean state.

Bluetooth (especially SPP or BLE) can sometimes
be in bad state. In this condition, it won’t reconnect

notifications are sent from the iOS to the watch
automatically (even when HOTWatch app is not
running). To connect BLE, bring the HOTWatch
app to foreground. BLE gets connected to the
watch. Once BLE connects, you will get BLE pair
request. It is very important to accept this pair
request for stable BLE connection.

BLE is supported in iPhone 4S or above with iOS
7 or above.

The notification size limit is 90 characters for
iPhone due to BLE limitation.

Please refer to advanced manual on iPhone
Bluetooth connection from www.hotsmart­watch.com/download for any BLE connection
issues.

Time and Information Screens

The user screens are divided into 4 main screens
(Time, Notifications, information Apps and custom

Apps) and Advanced Function Screens.

The Time and Information screens are divided into
4x6 sections as shown below. The 4 icons
represent 4 columns that have analog and digital
watch faces, notification screens, information and
custom apps. Within each column, there can be
up to 6 screens with different watch faces or
custom apps.
