1. Getting Started

For best user experience, download the HOT Watch app from the iTunes (iPhone) or Google Play
(Android phone) or Windows store (Windows phone). Install the app on your phone before you turn the
watch On.

2. Turning On and Off

To turn on the HOT Watch, press and release the power key. If it does not turn On, the battery may be
drained. Connect the watch to the charger and the watch should work. The watch comes with a
magnetic USB charger that pairs to the audio module of the watch.

Please do not leave the magnetic end of the charger near metal surface when USB end of the cable is
plugged in. It can create short to the USB lines. While we provide teeth to prevent short, angled metal
surfaces can still create short.

4. 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 below steps to get the best audio experience.

A. Wear the watch on your wrist, close to your palm. So that the speaker is closer
to palm.
B. Cusp the palm over the ear. Make sure that bottom of your palm is not
touching the ear: otherwise the sound will be blocked.
C. Adjust the volume (scale of 1-15) if required. The default volume level for
Hands-On is 5 and Hands Free is 13 for the call, default can be changed from the
HOT Watch app in the phone. Adjust the volume to the minimum required, for
audibility and for a better private call experience.
D.Volume can be further adjusted during call with + - buttons on the screen. The

watch automatically adjusts volume in noisy environments using auto gain.

5. Energy Optimization

gyroscope is switched Off by default to save battery power. It is switched On during a call or
whenever required. The gestures are categorized into call and non-call gestures. The call
gestures are activated during a phone call (ringing, dial-out, call in progress, etc).

Non-call gestures are used to get Recents, Favourites and Voice response. , Non-call gestures
are initiated by twisting the wrist two times. The non-call gestures are described below. The
non-call gestures are switched Off by default. They can be enabled in settings menu by
selecting All option for Gesture.

8. Audio Switching b/w Phone and Watch during Call

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 is done to ensure 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.

9. 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, phone book 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.

10. Notifications

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

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 size limit is 380
characters 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-GATT-ANCS is connected, these notifications are sent from the iOS to the
watch (even when HOTWatch appis not running). To connect BLE, bring the HOTWatch app to
foreground. The app will connect the BLE with watch. Accept BLE pair request from the
HOTWatch Application.

BLE is supported in iPhone 4S or above with iOS 7 or above. For older phone models/iOS only
SMS notification is supported with Bluetooth Message Access Profile (MAP). Select MAP on the
settings iPhone menu. Touching the SMS or MAP will toggle this selection.

To connect to MAP, tap on the tick adjacent to SMS. In Phone Bluetooth menu, navigate to the
connected device info and enable “Show Notifications”.

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